Fosroc Conplast SP440J

Conplast SP440J is a chloride free, superplasticising admixture based on selected sulphonated naphthalene polymers supported with other polymers. Main uses: - 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 labour costs without increasing water content. - Improved cohesion and particle dispersion minimizes segregation and bleeding and improves pumpability. - Chloride free, safe for use in pre-stressed and reinforced concrete.
