To accelerate the stiffening and early strength gain of Portland cement concrete and mortar.   Typical applications include concrete or mortar placed in cold weather and pre-cast concrete. Advantages   Particularly effective in assisting to offset the delaying effect of low temperatures on setting and strength gain.   Accelerated setting gives added protection against early age frost attack.   Also provides a degree of water reduction or increased workability.   Suitable for use in bricklaying mortar.   Chloride-free, safe for use in reinforced concrete. Standard compliance Conplast NC complies with ASTM C-494 as Type C and BS 5075 Part 1. Description Conplast NC chloride-free accelerating admixture is supplied as a light straw-coloured solution that instantly disperses in water. Conplast NC accelerates the early stages of cement hydration, producing more rapid stiffening and allowing strength gain to commence at an earlier stage. This effect is particularly noticeable at low temperatures and is most significant in the first 24 hours after mixing. Technical support Fosroc provides a technical advisory service for on-site assistance and advice on mix design, admixture selection, evaluation trials and dispensing equipment. Technical data and guidance can be provided for admixtures and other products for use with fresh and hardened concrete. Typical dosage The optimum dosage of Conplast NC to meet specific requirements should always be determined by trials using the materials and conditions that will be experienced in use. The allows the optimisation of admixture dosage and mix design and provides a complete assessment of the concrete

Water reducing admixture Uses   To improve the effectiveness of the water content of a concrete mix.   At higher dosages to provide a cost effective means of reducing concrete permeability and thereby reducing water penetration. Advantages   Allows specified strength grades to be met at reduced cement content or increased workability.   Water reduction significantly improves compressive strengths at all ages and enhances durability through the production of low permeability concrete.   Minimises the risk of segregation and bleeding and assists in the production of a dense, close textured surface, improving durability.   Chloride free, safe for use in pre-stressed and reinforced concrete. Standard compliance Conplast P211 complies with BS 5075 Part 1 and with ASTM C-494 as Type A. Conplast P211 complies with the requirements of the United Kingdom Water Fittings Byelaws Scheme and is listed in the Directory of Materials as suitable for use in contact with potable water under its previous name of Conplast P211. Description Conplast P211 is a chloride free water-reducing admixture based on selected sugar-reduced lignosulphonates. It is supplied as a brown solution which instantly disperses in water. Conplast P211 disperses the fine particles in the concrete mix, enabling the water content of the concrete to perform more effectively and improving the consistency of the concrete. This produces higher levels of workability for the same water content, allowing benefits such as water reduction and increased strengths to be taken. Technical support Fosroc provides a technical advisory service for on-site assistance and advice on mix design, admixture selection, evaluation trials and dispensing equipment.
