Fosroc Conplast SP431R

High performance superplasticising workability retention admixture. Main uses: - Particularly suitable for high performance concrete containing cements replacement products such as PFA, GGBFS and micro-silica and low water/cement ratio. - To provide excellent acceleration of strength gain at early ages and major increases in strength at all ages by significantly reducing water demand in a concrete mix. - To significantly improve the workability of site mixed and pre-cast concrete without increasing water demand. - To provide improved durability by increasing ultimate strengths and reducing concrete permeability. - Suitable for use in East and Central African conditions. Advantages: - Makes possible major reductions in water/cement ratio which allow the production of high performance concrete. - Increased workability levels are maintained longer than with ordinary sulphonated melamine admixtures. - Use in production of flowing concrete permits easier construction with quicker placing and compaction and reduced labor costs without increasing water content. - Major increases in strength at early ages without increased cement contents. - Improved cohesion and particle dispersion minimizes segregation and bleeding and improves pumpability. - Chloride free, safe for use in pre-stressed and reinforced concrete. - Brand: Fosroc - Technical datasheet available on request.
