23 Soil Testing - In-situ Sampling and Preparation
In-situ Sampling and Preparation
Sample Mixers
The correct sampling, description and preparation of
soil and soil mixtures is necessary if subsequent tests are
to be meaningful and provide representative results.
Various national and international Standards specify
a range of procedures and equipment necessary to
ensure representative sampling.
A regular laboratory requirement is the mixing of
samples with water and/or other constituents to provide
a homogeneous mixture prior to subsequent testing.
The following range of mixers provide an efficient
means of mixing samples.
With the use of simple hand tools, it is often possible to
obtain detailed information regarding the sub-surface
structure and hence the likely engineering characteristics
of the area under investigation.

24 Soil Testing - Soil Index Properties
Soil Index Properties
Soil index properties are used extensively by engineers
to discriminate between the different kinds of soil within
a broad category, e.g. clay will exhibit a wide range of
engineering properties depending upon its composition.
Classification tests to determine index properties will
provide engineers with valuable information when the
results are compared against empirical data relative to
the index properties determined.
Determination of Liquid Limit

The condition of a soil can be altered by changing
the moisture content. The liquid limit is the empirically
established moisture content at which a soil passes from
the plastic to the liquid state. A knowledge of the liquid
limit allows the engineer to correlate several engineering
properties with the soil. Two main types of test are used.
The Casagrande type (Cup), which has been used for
many years, and the cone penetrometer method, which is
now the definitive method specified in BS 1377.

The method is fundamentally more satisfactory than
the Casagrande method as it is essentially a static test
depending on the soil shear strength. The test is based
on the relationship between moisture content and
the penetration of a cone into the soil sample under
controlled conditions.

Determination of Plastic Limit
BS 1377, 1924-2, EN 1997-2; ASTM D4318; AASHTO
T90
The plastic limit is defined as the lowest moisture content
of a soil that will permit a sample to be rolled into
threads of 3 mm diameter without the threads breaking.
The test procedure has remained, in principle, the
same since 1932, when Casagrande proposed to
define the various limits by relating the moisture content
characteristics of soil under certain conditions. The
apparatus required is simple yet effective.
The majority of the apparatus required for this test is
standard laboratory equipment. For full details see the
Laboratory equipment section of the catalogue.

Determination of Shrinkage
Characteristics
When the water content of a fine-grained soil is
reduced below the plastic limit, shrinkage of the soil
mass continues until the shrinkage limit is reached.
Shrinkage can be significant in clays but less so in silts
and sands.
The equipment listed below enables the engineer to
determine a number of important parameters, including
shrinkage ratio, volumetric shrinkage and linear
shrinkage.
Volumetric Shrinkage
This method of test covers the determination of the
shrinkage limit, shrinkage ratio, volumetric shrinkage and
linear shrinkage.

Determination of Density, Particle
Density and Specific Gravity
The term density refers to mass per unit volume. The
density of a mass of soil is of interest to the engineer for
a variety of reasons including the design of earthworks
and foundations and in slope stability analysis.
Particle Density: Pyknometer Methods
BS 1377, 812-2, EN 1097-7, EN 1997-2; ASTM D 854;
AASHTO T 100
These methods are generally suitable for fine-grained
soils. The larger pycnometers are not usually suitable for
clay soils.
Particle density or specific gravity is a measure of the
actual particles which make up the soil mass and is
defined as the ratio of the mass of the particles to the
mass of the water they displace. A knowledge of the
particle density is essential in relation to other soil tests.
It is used when calculating porosity and voids ratio
and is particularly important when compaction and
consolidation properties are being investigated. The
majority of apparatus used for the various tests is general
laboratory equipment.

24 Soil Testing - Particle Size Distribution
Particle Size Distribution and
Sand Equivalent Value
The analysis of soils by particle size provides a
useful engineering classification system from which
a considerable amount of empirical data can be
obtained.
Two separate and different procedures are used.
Sieving is used for gravel and sand size particles and
sedimentation procedures are used for the finer soils.
For soil containing a range of coarse and fine particles
it is usual to employ a composite test of sieving and
sedimentation procedures.
The Sand Equivalent Test serves as a rapid field test to
show the relative proportions of clay-like or plastic fines
and dusts in granular soils and fine aggregates.

24 Soil Testing - Compaction and CBR
Compaction
Applications of Compaction
Many civil engineering projects use soils as fill material,
with soil normally being compacted to a dense state to
ensure that it has the optimum properties.
Soil used as fill:
Compaction on site is generally achieved by mechanical
means such as rolling, ramming or vibrating. Precise
control over the level of compaction is essential to
achieve best results at reasonable cost, with laboratory
compaction tests being used as they provide the basis for
control procedures that are subsequently used on site.
Compaction tests typically enable the following criteria
to be established:
◆
The relationship between dry density and moisture
content for a given degree of compactive effort.
◆
The moisture content for the most efficient
compaction; that is, at which the maximum dry
density is achieved under that compactive effort.
◆
The value of the maximum dry density achieved.
There are several different standard laboratory
compaction tests, with the most appropriate in each case
being based on the nature of the project, the type of soil
and the availability of equipment on site.

◆
To refill an excavation or void

BS 1377-4, 1924-2, EN 1997-2
This test method utilises a 2.5 kg hand compaction
hammer and a one litre capacity compaction mould.
Often referred to as the ‘Proctor’ test it is suitable for
soils containing particles no larger than 20 mm.
This test method utilises a 4.5 kg hand rammer
resulting in a heavier compactive effort than the 2.5
kg test method. Compactive energy some 4.5 times
greater is applied to the sample using the heavier
rammer.
The mould and hammer is manufactured from
corrosion protected steel components to withstand the
heavy usage involved in the test.
The method is often specified where higher levels
of compaction are necessary in a structure, e.g. an
airfield sub-base material.

California Bearing Ratio
A number of options are available to collect and
analyse data with the ELE CBR-Test 50.
The California Bearing Ratio test, or CBR test as it is
usually termed, is an empirical test first developed in
California, USA, for estimating the bearing value of
highway sub-bases and sub-grades. The test follows
a standardised procedure and there is little difference
between BS/EN and ASTM tests. However, there are
numerous ways of preparing samples and in this
respect American practice differs in detail from British
practice.
1
This test can be performed in the laboratory on
prepared samples or on location. It is important
to appreciate that this test, being of an empirical
nature, is valid only for the application for which
it was developed, i.e. the design of highway base
thicknesses.

25 Soil Testing - Consolidation
Consolidation
It is generally understood that clays and other
compressible soils can be subject to long-term
consolidation under the loads imposed by foundations
and above ground structures. Also that settlement may
occur even if the applied pressure is within the safe
bearing capacity of the soil.
Traditionally, consolidation has been measured with an
oedometer and this is generally known as the onedimensional consolidation test. We provide a range of
standard consolidation test equipment, with purposewritten software for precise and fast statistical analyses,
plus specially designed pneumatic and hydraulic
consolidation cells, together with a wide choice of
options.
25
One-dimensional Consolidation
The One-dimensional Consolidation test is used to
determine the consolidation characteristics of soils of
low permeability. Tests are carried out on specimens
prepared from undisturbed samples. Data obtained
from these tests, together with classification data and
a knowledge of the soils loading history, enables
estimates to be made of the behaviour of foundations
under load.
Vertical Settlement Measurement
Various methods of measuring vertical settlement
can be supplied. These range from dial gauges to
displacement transducers. All devices comply with
the accuracy specified in BS 1377, ASTM D2435 and
D4546. Displacement transducers are supplied with a
calibration certificate.
Consolidation Apparatus
The table below shows the range of devices available
for fitting to the EL25-0402 Consolidation Frame.

including:
Knowledge of the permeability characteristics of soil is
essential for construction projects where drainage is an
important element. In particular, permeability is a key
parameter for the design and assessment of landfill sites,
the investigation of contaminated ground, the design of
earth dams and sheet pile walls, and in assessing the
potential for lowering groundwater levels.

Compaction Permeameter
Clays and silts are tested using the falling head
technique. Flow of water through the specimen is
observed by monitoring the rate of fall of water in the
tube. It is essential that soils of very low permeability are
sealed inside the cylinder to prevent seepage along the
sides of the specimen. Before testing, the specimen must
be completely saturated with water as the presence of air
will restrict the flow of water.
These Permeameters are designed for performing either
constant head or falling head permeability tests on
undisturbed, remoulded or compacted soils.

This combination permeameter has a transparent plastic
chamber for soil specimens of either fine-grained or
coarse-grained soils. Generally, soils containing 10
percent or more particles passing a 75 μm sieve are
tested using the falling head assembly. More granular
soils, containing 90 percent or more particles retained
on the 75 μm sieve, are tested using the constant head
assembly.
The cell is sealed at the top so that a vacuum may be
used to saturate the specimen. Porous stones located at
the top and bottom of the cell prevent sample flaking or
washout.
For constant head tests, a plastic funnel reservoir is
mounted on an upright attached to the cell, providing
a maximum head of 550 mm. Falling head tests are
performed using the graduated pipette falling head
reservoir, which gives a maximum head of 1000 mm and
is graduated 0.2 ml.

soil matrix flux potential. These three factors govern how
liquids will move through an unsaturated soil profile.
Recent significant advances in both the theoretical
and practical techniques of measuring soil hydraulic
conductivity have been made by the University of Guelph,
Canada. This has resulted in the development of the
Guelph Permeameter, utilising the Constant Head Well
principle.

25 Soil Testing - Soil Strength (Triaxial)
Soil Strength (Triaxial)
The measurement of total stress or effective stress
requires different procedures and therefore different
equipment.
Total stresses are normally measured in a triaxial cell
where the sample is subject to an all round confining
pressure ( 3). A load is applied ( 1) through a piston
onto a pressure pad, with the sample being confined
within a rubber membrane so that no drainage in or out
of the specimen is allowed. Pore water pressures are
not normally measured and the undrained test is often
referred to as the QU-TXL test.
An extension of the QU test is the unconsolidated
undrained test (UU); this is similar to the QU test but
is run at a slower rate in order to measure pore water
pressure.
By comparison, effective stresses when measured in
a triaxial cell are more complex in their nature, as
numerous parameters can be measured. These include
back pressure, pore water pressure and volume change;
all of which can be used to calculate the required
engineering properties.
Effective stress tests are usually referred to as
consolidated drained (CD) or consolidated undrained
(CU). Generally the CD test is applicable to sands, while
both the CU or CD test can be used with clays. There
are many special test variations within these basic test
groupings.
Our range of triaxial cells and accessories, used in
conjunction with other equipment such as load frames,
pressure sources and measurement devices, have
been specifically designed to meet the wide ranging
requirements of modern soil mechanics laboratories.
Each system is easy to set up and use, providing accurate
and repeatable measurements.

Quick Undrained Triaxial tests
Unconfined Compression tests
Electronic measurement is achieved using the optional
EL27-1200/09 Electronic Control and Readout Unit
(ECU) and appropriate load and axial displacement
transducers, see catalogue Section 27. With digital
readout, data logging capability and download software
included as standard, the Multiplex 50/ECU combination
provides unique features safeguarding not only the
testing equipment, but also test integrity and accuracy.
Among these, the ECU will check its testing mode (CBR,
Marshall, etc) against the frame speed setting and will not
permit the test to run if these settings are incompatible.
The ECU automatically configures its logging rate for
each test type to comply with BS, ASTM or AASHTO
Standards. This means the data exported from the ECU
needs no further manipulation before analysis and
reporting. Finally, if the upper limits of the transducers are
exceeded, the ECU stops the load frame to protect the
test accessories and load frame drive system.

use of special lubricant to reduce friction to a minimum
and eliminate water leakage.
The piston load capacity is designed to accept high
horizontal forces which may be present during the final
stages of a test.
Each cell has five take-off positions drilled in the base for
top drainage/back pressure, pore water pressure and
bottom drainage.
Two no-volume change valves and an anvil for strain
gauge/transducer datum are supplied for fitting to
the cell.
A feature of these cells is that they all accept a single
diameter piston. The internal height is such that a range
of submersible load transducers can be fitted without
any modification. Each cell will accept a range of base
adaptors and various accessories for testing a wide
range of specimens.

De-aired Water
It is particularly important that water from which dissolved
air has been removed is used in the pore pressure
measurement system and saturation procedures. Any
dissolved air in the water will lead to errors in the
measurement of pore pressure, particularly at low
pressures, and also give slow or incorrect saturation
results.
ELE De-aired Water Apparatus
BS 1377
This compact self-contained unit will de-air water
quickly and efficiently down to levels of dissolved oxygen
acceptable for geotechnical test methods.
Air is removed from the water by a vacuum system, which

26 Soil Testing - Pressure Systems
Pressure Systems
Pressure Reducing Panels and
Bladder Assemblies
The provision and use of constant pressure systems
in the geotechnical laboratory is essential if testing
methods and equipment are to be fully utilised.
Generally a number of independent and variable
pressure sources will be required in a laboratory.
Accurate and reliable monitoring systems will also be
required, which may range from a single pressure
gauge through a whole series of transducers.
Compressed air must be controlled and delivered to a
system designed to transfer the controlled pressure to
the fluid (usually water), which applies the various test
pressures, e.g. a confining pressure in a triaxial test.
We offer a range of products designed to supply and
monitor all those parameters necessary for the successful
testing of geotechnical materials. Two types of constant
pressure systems are available:
1.
2.
Air/water system operated by a pneumatic
compressor
A motorised oil/water system
Air/Water Constant Pressure
System
Where a laboratory requires a number of constant but
independent and variable pressure sources, the use of a
pneumatic compressor is recommended. Depending on
the capacity and volume of the unit, a series of pressure
sources can be provided to various test stations around
the laboratory. Two sizes of compressor are available.
700 kPa Air Compressor Unit see EL83-1730/01
1000 kPa Air Compressor Unit see EL83-1735/01
The pressure reducing panels are used in conjunction
with a bladder-type air/water interface assembly. Each
individual pressure take off from the reducing panel will
require a bladder interface assembly.
Connection of the reducing panels to the compressor/
water trap outlet and to other reducing panels requires
the use of EL26-1769 Nylon Tubing.

26 Soil Testing - Direct Shear and Vane Tests
Direct Shear and Vane Tests
Every building or structure that is built in or on the earth
imposes loads on the soil supporting the foundations.
The stresses set up in the soil cause deformation of the
soil with stress failure being caused by slippage of soil
particles, which may lead to sliding of one body of soil
relative to the surrounding mass.

EL26-2114/02 for 110 – 120 V AC, 50 – 60 Hz, 1 ph.
The process is known as shear failure and occurs
when shear stresses set up in the soil mass exceed the
maximum shear resistance that the soil can offer, i.e. its
shear strength.

29 Soil Testing - Bearing Capacity
Bearing Capacity
The design of foundations is a prerequisite of economic
design and construction. In order to guard against shear
failure and unacceptable ground movements due to
loading it is often necessary to determine the ground
bearing capacity.
Dynamic Cone Penetrometer
The TRL (Transport Research Laboratory) Dynamic
Cone Penetrometer (DCP) is used for rapid in-situ
measurement of the structural properties of existing road
pavement constructed with unbound materials. The unit
incorporates an 8 kg weight with a drop of 575 mm, and
a 20 mm diameter cone fitted to the end of the shaft,
allowing measurements to be made down to a depth of
approximately 850 mm.
Readings are usually taken after a set number of blows,
changing the number according to the strength of
the layer being penetrated. For good granular bases,
readings every five to ten blows are satisfactory, but for
weaker sub-base layers and subgrades, readings every
one to two blows may be appropriate.
The DCP requires three operators, one to hold the
instrument in a vertical position, one to raise the hammer
and let it fall and one to record the results. A typical
test takes only a few minutes, providing a very efficient
method of obtaining information which would otherwise
require the excavation of test pits. Where pavement layers
have different strengths, boundaries can be identified and
layer thickness determined.
EL29-3720 Dynamic Cone Penetrometer supplied
complete with all necessary tools, assembly and
operating instructions. Assembled height 1965 mm,
assembled weight 20 kg.
EL29-3729 ELE Pocket Penetrometer
Pocket Penetrometer
A lightweight device for determining the approximate
unconfined compressive strength and the estimation of
shear strength, it can also be used to classify cohesive
soils in terms of consistency.
The stainless steel plunger is pushed into the soil until the
penetration mark is reached. The equivalent unconfined
compressive strength of the soil can be read in kgf/cm2 or
tons/ft2 from the maximum load indicator provided.
Important: the readings obtained from the pocket
penetrometer do not replace laboratory test results due
to the fact that a small area penetration test is inherently
liable to give misleading results. The instrument should
not be used for obtaining foundation design data.

100 mm Pouring Cylinder
In-situ Density
BS 1377, 1924
Many civil engineering projects require the use of fill
material. Whenever soil is placed as an engineering
fill, it is usually compacted to a dense state, to obtain
satisfactory engineering properties. Compaction on
site is usually effected by mechanical means such as
rolling, ramming or vibrating. Control of compaction is
necessary to achieve a satisfactory result at reasonable
cost. Laboratory compaction tests provide the basis for
control procedures used on site.

Concrete
What is Concrete?
Concrete is perhaps the most versatile of all construction
materials. In its freshly mixed condition it can be
poured, pumped and moulded into a variety of forms
and shapes, while in its hardened state it can be used
for many construction purposes.

The quality of concrete is crucial if structures are to
be safe and serve the purpose for which they were
designed. Our concrete testing equipment gives you
the ability to measure and prove the quality of each
batch of material, so that you can ensure the correct
application of the key raw materials.
Cement
Cement is a man-made material and can be supplied in
many forms, with different cements having specific and
often varied properties, such as rapid hardening, sulphate
resistance and low heat.
The precise cement content for different batches of
concrete will normally be specificed at the time of
manufacture; typically, concrete has a cement content of
about 250 kg/m3.
Sections 38 and 39 describe test equipment specifically
designed for the testing of cement.
Aggregate
By far the greatest proportion by volume of concrete is
made up of aggregate. This can be naturally occurring,
such as river gravels, or crushed rock from quarrying
operations; other materials can also be substituted for
aggregate including colliery waste and recycled concrete.
Normally, coarse and fine aggregates are used in the
proportions of approximately 70:30.
Section 42 describes test equipment suitable for the
testing of concrete aggregates.
Water
Water reacts with cement and allows the necessary
hydration and hardening process to proceed. The quality
of water is not generally critical providing it is clean and
free from impurities and high silt content. The quantity of
water added does, however, have a major effect on the
quality and strength of the concrete.
Test equipment designed to determine the effect of water
on fresh concrete is described in Section 34.
59
34 Concrete - Fresh and Hardened Concrete Testing
Sampling, Consistency and
Workability
The correct sampling and mixing of fresh concrete
is important if test results are to be reliable. Most of
the equipment necessary for efficient sampling and
mixing is standard laboratory equipment detailed in the
Laboratory Equipment section of this catalogue.
To ensure that concrete achieves its maximum possible
strength and yet retains its ease of placing on site, it is
essential that the design of the concrete mix, in relation
to the water-cement ratio and workability, is closely
controlled.
Slump Test

Test appropriate for concrete mixes of low and very
low workability
This method is a mechanised variation of the slump
test and includes a determination of the workability of
concrete. It is based on the principle of subjecting the
concrete to vibration after removal of the slump cone.
The assembly is mounted upon a small vibrating table
operating at a fixed amplitude and frequency. The time to
complete the required vibration gives an indication of the
concrete workability.
Special Note: The consistometer must be operated from
an electrical supply of 50 Hz in order to comply with the
fixed test frequency specified.

Air Entrainment
The determination of air content of freshly made
concrete is detailed in EN 123450 and ASTM C236,
where the importance of two main applications
is highlighted. The primary purpose of entraining
air in concrete is to give the required resistance to
weathering. The use of chemical additives to increase
the workability of concrete often requires an air content
check to be made.

Mixing Equipment
The efficient mixing of concrete prior to moulding
specimens in the laboratory for subsequent testing is
essential if quality specimens are to be manufactured.
The object of mixing is to coat the surface of all
aggregate particles with cement paste, and bring
the mix to a uniform condition. Pan or rotating drum
mixers are suitable for the mixing of small quantities of
concrete, which are generally used in a laboratory.

Moulding Equipment
Test procedures require that specimens are cast in a
number of standard sizes convenient for compressive
and flexural strength determination. The engineering
tolerances specified for moulds are very stringent and
the internal finish of the surface must be of a high order
to comply with the recommendations laid down in many
International Standards. Moulds must not deform during
manufacture of concrete specimens if the specimen
dimensions are to be maintained.

Vibrating Poker
Compaction
EN 12390-2 12350-6, -7
The strength, durability and finish of concrete rely
in part on the adequate compaction of the mix. An
increasing number of contract specifications call for
various forms of vibro-compacted concrete as a means
to achieve a better and more consistent mixture. It
should however be remembered that fluid mixes may
segregate when vibrated in which case it may be more
appropriate to compact using a tamping bar or rod
during laboratory mix design.
The ELE vibrating table is a compact unit providing
controlled vibro-compaction in the laboratory, using cube
or cylinder moulding equipment.

Curing of Specimens
The correct environment for curing concrete test
specimens is important to achieve consistent and
reproducible test results. Two primary factors must be
taken into consideration to satisfy the requirements,
namely to maintain a stable temperature and to prevent
loss of moisture from the specimen.
A standard curing temperature of 20ºC is usually
specified and should be maintained at the required
degree of accuracy. The use of water to prevent loss
of moisture is the method most commonly used. In
tropical climates a curing temperature of 25ºC is often
acceptable.

Capping of Cylinders
When conducting a compressive strength test on a
concrete cylinder it is important that the ends of the
specimen are flat and parallel to each other. The
trowelled face of a prepared concrete cylinder, or both
ends of a concrete core, will require treatment to obtain
these conditions.
Sulphur Compound Method
EN 12390-3
The sulphur compound method is a hot process and
offers a considerable saving in time and labour over the
mortar capping method. The method is virtually instant
and the compound can often be recovered for further
use.
Warning: The sulphur compound, when hot, will give off
sulphur fumes, and therefore it is important that good
ventilation, or preferably a fume cupboard, is available in
the laboratory.

The density of both fresh and hardened concrete is of
interest to the engineer for numerous reasons including
its effect on durability, strength and resistance to

Hardened concrete density is determined either by
simple dimensional checks, followed by weighing and
calculation, or by weight in air/water buoyancy methods.

Pulse Velocity Measurement
It has been designed with site testing particularly in mind
and is simple to operate, with a high order of accuracy
and stability.
The basic principle of this method of testing is that
the velocity of an ultrasonic pulse through concrete is
related to its density and elastic properties. Some care
is necessary when testing, but an experienced operator
may obtain a considerable amount of information about
a concrete member. The advantage of this method is
that the pulse passes through the complete thickness
of the concrete so that the significant defects can be
detected.
The majority of concrete testing will require transducers
with a frequency of 54 kHz.

37 Concrete - Flexural and Transverse Machines and Accessories
Flexural and Transverse Testing
Machines and Accessories
The flexural and transverse strength of concrete is of
interest to engineers for many reasons. Movement of
structures which may be induced by e.g. temperature
changes, ground vibrations, cyclic loading of road
pavements and many other external influences, will set up
internal stresses within a concrete member.
There is no clearly defined relationship between
compressive and flexural strength. Generally it can
be assumed for most purposes that flexural strength
of normal concrete is about 10% of the compressive
strength achieved in the same concrete.
Modern concrete technology utilises a wide range
of materials such as glass or steel fibres to improve
the flexural strength of the concrete. These modified
concretes often require the use of special tests and
equipment.
Lower loads are used to test concrete in flexure; however,
the shape and size of test specimens is such that larger
and often heavy specimens can be difficult to handle. ELE
has designed the range of machines offered to provide
for ease of specimen positioning and subsequent testing.
The range of flexural test equipment offered provides a
wide variety of choice and test methods including low
strength compression tests using optional ball seating
assemblies.

The first use of lime as a cementing material is not
recorded but it was certainly used in ancient Egypt and
also by the Romans. In more recent times, there are
records that lime, combined with a pozzolan from Italy,
was used in the construction of the Eddystone lighthouse
as early as 1756.
Today, cement is manufactured by a chemical process
with raw materials being crushed, ground and blended
before being heated in a rotary kiln until they combine
chemically. The clinker from the kiln is then ground with
gypsum to form Portland cement.
Our cement testing systems provide efficient and reliable
methods of measuring all of the key criteria to ensure
consistent, high quality cement manufacture.

38 Cement - Fineness
Fineness
The fineness of cement is a property that must be
carefully controlled during the manufacturing process.
The total specific surface of the cement represents the
surface area available for hydration. Various methods
are in use to measure the specific surface of cements.
For most purposes air permeability methods produce
accurate, repeatable results.

Automatic Vicat
Determination of setting time and soundness of cement
requires the use of a neat cement paste of standard
consistence. The Vicat method is usually specified as
the test used to determine the water content which will
produce the desired consistence.

38 Cement - Soundness
Soundness
Soundness of Cement Paste by the
Le Chatelier Method
The soundness of cement and hydrated lime is of
particular importance. It is essential that once hardened
the paste does not undergo a large change in volume.
EN 196-3, 459-2
The soundness of cements and limes can be determined
by an expansion test using Le Chatelier Moulds. The
method of curing lime differs from that of cements, lime
being cured in a steam tank and cements in a water bath.
The ASTM method uses a high-pressure steam vessel
(Autoclave) to cure the specimens.

39 Cement - Mixing, Moulding, Curing and Strength
Mixing
The results of strength testing of cement and other
materials such as Lime and Fly Ash are dependent
on the method and the quality of equipment used.
A standard system for strength testing is based on
compressive strength of mortar prisms.
In the USA, ASTM C109 and C190 are the definitive
methods for determining compressive and tensile
strength. The BS 4550 method using either 70.7 mm
or 100 mm cubes has been retained in the UK only for
comparative purposes. EN196-1 is now the definitive
method.
The results of strength testing are dependent not only
on method but also on the quality and accuracy of
the testing machine used to determine compressive or
flexural strength.
The correct mixing sequence and homogenity of mix
is important if consistent, repeatable test results are
to be obtained. Mixers should be powerful enough to
ensure that the motor’s speed is not affected by the mix
constituents and designed to ensure that the mixer action
and blade does not break down individual sand particles
and preferably provide automatic mixing cycles.

42 Mechanical Properties
Aggregates comprise a significant proportion of all
materials used in the many different construction
processes, so it is important to determine the properties
of different types of aggregates through effective testing
and measurement.
The required properties will vary from project to project,
for example, resistance to polishing will be unimportant
in a pavement base course but will be crucial in a
wearing course. However, the key criteria throughout are
accurate and repeatable test procedures, and our range
of aggregates testing equipment has therefore been
designed to help you determine a wide range of factors.
These include: particle size, shape and texture; relative,
bulk and compacted densities; soundness and resistance
to chemical attack; and mechanical properties.

42 Aggregates - Sampling and Preparation of Aggregates
Sampling and Preparation of
Aggregates
Particle Size and Shape
Sampling and preparation of aggregates and fillers is
necessary for a variety of reasons including research,
design and quality control. The main aim of sampling is
to obtain a sample representative of the average quality.
Sampling techniques and procedures are described
in various Standards including BS 812:Part 101 and
102 and ASTM D75. Individual items of equipment
necessary for sampling and preparation are described
in the Soils Section of the catalogue.
Among many of the applications to which aggregate
lends itself is its use in economical concrete mixes,
impervious, durable asphalts, macadams and road
bases. Particle size, shape and texture can have
considerable effects on various design properties and
are generally specified within certain limits. Rounded
aggregate can lead to instability in a bituminous
mixture yet be ideal as a concrete aggregate where
good workability of the mix is essential for placing and
compaction.
Drying and Weighing
Determination of Particle Size
EN 932-2
EN933-1, BS 812; ASTM C136
Most test techniques involve the use of drying ovens
and balances. A comprehensive range of equipment is
described in the Laboratory Equipment Section of the
catalogue.
A comprehensive range of sieves, sieve shakers and
ancillary equipment will be found in the Laboratory
Equipment Section of the catalogue. The range of sieves
offered includes ISO 3310, BS 410 and ASTM E11 mesh
sizes and frames.
Moisture Content
The moisture content of aggregate is of importance e.g.
when batching concrete or when compacting unbound
materials to achieve a specified density. Accurate means
of determining moisture content are specified in various
Standards and include methods suitable for use in the
laboratory or on the construction site. Individual items of
equipment necessary for determining moisture content
are described in the Soils Section and the Laboratory
Equipment Section of the catalogue.

42 Aggregates - Determination of Flakiness and Elongation
Determination of Flakiness and
Elongation
Aggregates which are flaky and/or elongated will often
lower the workability of a concrete mix and may also
affect long term durability. In bituminous mixtures flaky
aggregate makes for a harsh mix and may also crack
and break up during compaction by rolling.

42 Aggregates - Density, Voids and Bulking
Density, Voids and Bulking
As with any porous material, the value obtained for
the particle density of an aggregate will depend on the
method of test and apparatus used. Different particle
sizes within a sample often have different particle
densities. The term particle density expressed in Mg/
m3 is numerically equal to the specific gravity. Various
methods, depending upon the type and size of material
to be tested, are specified in Standards for testing
aggregate.

42 Aggregates - Soundness and Chemical Tests
Soundness and Chemical Tests
The presence of organic matter and certain chemicals
can have a considerable influence on the strength and
durability of concrete. The ability of aggregates to resist
excessive change in volume (soundness) due to physical
changes in the environment is also of importance.
Knowledge of these potentially harmful factors will
ensure that precautions can be taken at the mix design
stage of a project.
Chloride Content: Rapid method
Quantab chloride titrators can be used for estimating the
chloride content of aqueous solutions. They are suitable
for site testing and quality control of aggregates requiring
less than 30 minutes to obtain a result.

for determining sulphate ions in aqueous solutions.
Sulphate test strips are convenient measuring devices for
preliminary assessment of sulphate content.

900 mg/l. Pack of 100. Weight 10 g
Soundness of Aggregates
BS 812; ASTM C88; AASHTO T104; EN 1367-2
The soundness of aggregates to physical changes
caused by the environment is important to the long-term
durability characteristics of concrete. Excessive changes in
volume can be caused by freezing and thawing, thermal
changes at temperatures greater than freezing, and cycles
of wetting and drying.
Hydrometers and Wire Baskets see Laboratory
Equipment Section.
Organic Impurities in Fine
Aggregate
ASTM C40
If aggregate contains organic impurities it may not be
suitable for inclusion in concrete. Organic impurities,
usually tannic acid and its derivatives, may interfere with
the chemical reactions of hydration. Impurities are more
likely to be found in fine (sand) aggregate.

42 Aggregates - Mechanical Properties
Mechanical Properties
The diverse range of aggregates available to the
engineer makes it essential to select a material that
is adequate for a given application. The following
equipment is designed to determine various mechanical
characteristics that need to be known in order to select
the most suitable and economic type of aggregate.
Aggregate Impact Value (AIV)
BS 812-112
The apparatus has been designed in a particularly heavy
duty form, with specially hardened steel surfaces for
minimum wear. The assembly is heavily plated to ensure
corrosion resistance and forms a rigid frame around
the quick-release trigger mechanism which ensures an
effective free fall of the hammer when released.
Aggregate Crushing Value (ACV)
and Ten Percent Fines Value (TFV)
BS 812-110, 111
These tests are a measure of the crushing properties of
aggregate and use the same basic equipment. The ACV
test requires a standard load of 400 kN to be applied
over a period of 10 minutes while the TFV test measures
the force required to produce a specified depth of
plunger penetration.

The main engineering use of bituminous materials is for
road construction, with the material consisting primarily
of two ingredients: aggregate and binder.
The term Asphalt is simply one of two generic names
used to classify or describe bituminous mixtures; the
other being Macadam. In the USA the term Asphalt
denotes what in the UK is known as Bitumen.
Within these two broad groups lie an almost infinite
number of mixtures which can be specified to suit
particular engineering requirements. Our latest testing
equipment has therefore been developed to enable
construction engineers and laboratory staff to carry out a
wide range of industry standard tests quickly, simply and
reliably.
Our range of manual and automatic equipment allows
you to determine properties that include optimum binder
content, aggregate grading and void content, using
traditional methods such as the Marshall test.

Peak load and the corresponding flow
Windows® download software supplied
User-selectable SI, Metric and Imperial Units
ECU features large character LCD display
A limitation of using conventional dial gauges in the
Marshall test is the difficulty of accurately synchronising
the measurement of flow with that of peak load reading.
To overcome this limitation the Marshall Test 50 load
frame can easily be fitted with optional electronic load
and flow measurement transducers connected to
EL27-1200/09 (E)lectronic (C)ontrol (U)nit for simpler test
operation and data recording.
At the end of a test the ECU will automatically hold the
maximum load and flow readings enabling test data to
be downloaded to a PC using the Windows® software
supplied as standard with ECU.
Analysis and reporting can then be easily created in MS
Excel or equivalent software.
The ECU can be programmed to automatically stop
the load frame should transducer limits be exceeded,
protecting test accessories and load frame drive system.

The equipment comprises a tray 300 mm square which,
when used in conjunction with a specially calibrated
spring balance, will determine the rate of spread of
coated chippings in terms of kg/m2. The spring loaded
balance will accept rates of spread between 4 and
16 kg/m2.
Between 5 and 10 trays are positioned in the path of

Triaxial and Permeability
Strength
Rock mechanics is the theoretical and applied science
of the mechanical behaviour of rock; in particular the
response of rock to changes in stress distribution, both
below and adjacent to a structure or excavation.
Carrying out complex and expensive in-situ tests to
determine rock engineering parameters is generally
uneconomical in all but the largest construction projects.
By comparison, laboratory testing, combined with simple
yet efficient field test equipment, offers an effective and
reliable alternative.
Our range of rock testing equipment has therefore been
developed to help you identify, prepare and accurately
and reliably test rock samples using industry standard
testing techniques.

Permeability of Rock
Investigating the permeability or flow of water through
rock subjected to high confining pressures is often
necessary. The capacity of a rock mass at depth to
transmit or yield water is of particular importance when
designing deep structures such as tunnels.
Permeability end caps used with ELE-Hoek Cells and
constant pressure systems are a cost-effective solution
suited to investigating the permeability of rock at high
confining pressures in the laboratory.

80 Laboratory Equipment - Sieve Shakers
Sieve Shaker
Hand sieving of a large number of samples can often be
tedious and sometimes lead to inaccuracy of results. The
following machine provides a wide choice of options for
the busy laboratory.
ELE Sieve Shaker
EN 932-5
The ELE sieve shaker is powered by an electromagnetic
drive that has no rotating parts to wear making it
maintenance free and extremely quiet in operation.
The unit features a triple Vertical-Lateral-Rotary vibrating
action that moves the sample over the sieve producing
faster more efficient sieving, while the rapid vertical
movements also help keep the apertures from blinding.
The shaker is ideal for laboratory or on site use. It
is robust, compact and sufficiently lightweight to be
portable. The separate digital microprocessor controlled
console unit incorporates a keypad for setting the sieving
program and is isolated from any effects of vibration
from the shaker.
EL80-0200/01 ELE Sieve Shaker
As standard the shaker includes, timer 0-999 minutes,
adjustable vibration intensity and adjustable intermittent
or continuous operation.
The unit accepts up to ten 200 mm or 8 inch, full height,
diameter sieves and lid and receiver, or up to six 300 mm
or 12 inch diameter sieves and lid and receiver.
EL80-0200/01 ELE Sieve Shaker complete as specified.
Dimensions (l x w x h) 380 x 440 x 1085 mm.
Weight 65 kg. For 220 – 240 V AC, 50 Hz 1ph.

85 Mobile Laboratories
Trailer-type Mobile Laboratory
Our mobile laboratories make it easy to carry out
on-site surveys quickly and easily, especially in remote
locations where normal laboratory and testing facilities
may not normally be available.
Each mobile laboratory can be set up to meet the needs
of different applications and is normally fitted with the
standard ELE construction materials testing equipment
found in this catalogue. The configuration shown in
this catalogue section uses standard fittings within the
laboratory to provide ample working and storage space.
As mobile laboratories can be used for many different
purposes, and can be fitted with a wide range of
equipment, we also offer a custom design facility to
meet your exact needs.
Applications
Soils
Site Investigation
On-site Design
Soil classification
Site survey
Pavement design
On-site facilities enable both physical
and chemical testing to be carried
out on soil samples, ensuring rapid
and accurate classification.
The use of a mobile laboratory is a
cost-effective solution to enable
surface and subsurface conditions to
be investigated at an early stage in
the planning and design process.
Mobile laboratory units can provide
an efficient method of gathering
data from site investigations. This
offers a practical method for
designing road pavements on site,
with testing and variations to the
design being immediately available
to site engineers.

be bound to accept the goods when they become available. The
Company shall not be liable for any loss or damage or delays in
transit or consequential losses or losses including loss of profit
resulting in any way in respect of late delivery howsoever caused

accordance with Incoterms 2000. Where the terms of sale are
P&D, risk in the goods shall pass to the customer when the goods
leave the Company’s premises.
(b) Title in the goods remains vested in the Company and shall only
pass from the Company to the Customer upon full payment being
made by the Customer of all sums (due on whatsoever account or
grounds) to the Company. In the event of the goods being sold

unencumbered right to sell the goods. Such warranty specifically
includes the Company’s ownership of the necessary patent rights

otherwise shall be deemed to grant to the Customer the right to
manufacture or in any way reproduce the goods or reproduce or
use any intellectual property rights of the Company or its agents.
(b) No representation or warranty is given as to the suitability of
the goods for any particular purpose and the Customer shall satisfy
himself in this respect and shall be totally responsible therefor.
(c) Unless otherwise notified by the Company all goods supplied
shall have a twelve month warranty commencing from the date of
invoice. In circumstances where the Company notifies the Customer
of an alternative warranty period, such alternative shall prevail over
any other warranty period.
(d) In the case of any goods not manufactured by the Company
but supplied by them or incorporated within the Company’s goods
the Company is unable to provide any warranty but will where
possible assign to or pass on to the Customer the benefit of any
such warranty that the Company shall itself have received from its
own supplier.

warranty as to the fitness of any packing for storage purposes or
any other purpose other than the transport of the goods to the
named contract destination.
11 Liability
(a) Nothing herein shall be deemed to exclude or restrict the
Company’s liability for death or personal injury resulting wholly
from the negligence of the Company.
(b) The Company shall not be liable for any consequential or
indirect loss suffered by the Customer whether this loss arises from
a breach of duty in contract or tort or in any other way, including
loss arising from the Company’s negligence. Non-exhaustive
illustrations of consequential or indirect loss would be :
(i) Loss of profits.
(ii) Loss of contracts.
(iii) Damage to property of the Customer or anybody else.
(iv) Personal injury to the Customer or anybody else (except so far
as such injury is wholly attributable to the Company’s negligence).
(c) The Customer hereby agrees to indemnify the Company against
all claims made against the Company by any of the Customer’s
employees, Customers or any other person for which liability would
have been excluded by this clause if the claim had been made
against the Company by the Customer.
(d) The Company shall not be liable in any way for any damages
direct or consequential as a result of use of the equipment for
any purpose other than that agreed nor for any use not stated
and agreed in the Company’s specifications nor for any fault or
defect arising from the Customers failure to disclose relevant and
pertinent information to the Company. Where the purpose of the
goods is misrepresented or omitted the Company shall be under no
obligation in any manner and responsibility and liability shall pass
to the Customer.
(e) The Company shall not be liable in any way for any damage
direct or consequential arising as a result of the failure by the
Customer to comply with the terms of the operating manual
supplied with the goods or by reason of a failure by the Customer
to comply with the specified requirements for maintenance and
calibration of the goods.
(f) The Customer acknowledges that the proper use of the goods
can only be made by appropriately trained operatives. Training
in the use of the equipment provided by ELE is available on a
chargeable basis. Accordingly, the Company shall not be liable
in any way for any damage direct or consequential, arising as
