n o A m P a / n 6 y D SR Superplasticizer with retarding effect based on modified acrylic for ready-mixed concrete with a low water/cement ratio and long water retention even in hot climates DESCRIPTION OF PRODUCT Dynamon SR 6/PA is a modified acrylic-based admixture for ready-mixed concrete, belonging to the MAPEI Dynamon SR system. WHERE TO USE Concretes manufactured with Dynamon SR 6/PA have a high level of workability (consistency classes plastic or fluid according to ASTM standard), and are consequently easy to apply when fresh. At the same time they offer excellent mechanical performances when hardened. Dynamon SR 6/PA is especially recommended for the ready-mixed concrete sector and whenever a considerable reduction in mixing water is required, coupled with excellent maintenance of initial workability of the concrete in various consistency classes, even when surrounding temperature is high. The main application areas for Dynamon SR 6/PA are: • ready-mixed concrete with long slump retention, especially in hot weather; • concrete for waterproof, durable applications according to the specified exposure class; • RCC. TECHNICAL CHARACTERISTICS Dynamon SR 6/PA is a water solution containing acrylic polymers (without formaldehyde), capable of dispersing the grains of cement and promoting slow development of initial cement hydration. HOW TO USE Dynamon SR 6/PA develops maximum dispersing action when added after the other mix ingredients (cement, aggregates, added minerals or filler materials and at least 80% of the mixing water). COMPATIBILITY WITH OTHER PRODUCTS Dynamon SR 6/PA is compatible with other products for producing special concrete, and especially with: • Mapeplast SF silica fume based powder admixture for manufacturing “top quality” concrete (high strength, impermeability, durability); • Expancrete, expansive agent for manufacturing shrinkage compensated concrete; • fly ash for the production of conventional concrete or self-compacting concrete; • Mapeform Eco and DMA 1000 form-release agents for release concrete from formworks; • Mapecure curing agents to protect concrete structures from rapid water evaporation. DOSAGE Dosage by volume: from 0.6 to 1.2 l per 100 kg of cement for conventional concrete. Different dosages from those suggested must be previously tested through concrete trials, in addition to consulting MAPEI Technical Services Department. PACKAGING Supplied in bulk quantities and 1,000 l IBC tanks. STORAGE Dynamon SR 6/PA can be stored for 12 months in TECHNICAL DATA (typical values) Consistency: liquid Colour: brown Density according to ISO 758 (g/cm³): 1.11 ± 0.03 at +20°C pH: 6.0 ± 1.0 Main action: water reduction and/or improved workability, retention of workability in hot weather Collateral action: retarding of initial setting time, workability retention Classification according to EN 934-2: high range water reducing, hardening accelerating, superplasticizer, tables 11.1 and 11.2 Classification according to ASTM C494: type G standard Classification according to ASTM C1017: type II Chlorides soluble in water according to EN 480-10 (%): < 0.1 (absent according to EN 934-2) Alkali content (Na₂O equivalent) according to EN 480-12 (%): < 3.0 sealed containers, protect from frost. Exposure to direct sunlight can provoke variations of the colour tone without altering in any way the performances of the product. SAFETY INSTRUCTIONS FOR PREPARATION AND APPLICATION Dynamon SR 6/PA is not considered as dangerous according to the current regulations regarding the classification of mixtures. It is however recommended to use protective gloves and goggles, and to take the usual precaution when handling chemical products.
