Fosroc Conplast SP425-L

Superplasticiser - high performance superplasticising admixture Main uses: - 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. - Particularly suitable for precast concrete and other high early strength requirements. - To significantly improve the workability of site mixed and precast concrete without increasing water demand. - To provide improved durability by increasing ultimate strengths and reducing concrete permeability. - Major increases in strength at early ages without increased cement contents are of particular benefit in precast concrete, allowing earlier stripping times. Advantages: - Major increases in strength at early ages without increased cement contents are of particular benefit in precast concrete, allowing earlier stripping times. - Makes possible major reductions in water: cement ratio which allow the production of high strength concrete without excessive cement contents. - Use in production of flowing concrete permits easier construction with quicker placing and compaction and reduced labour costs without increasing water content. - Increased workability levels are maintained for longer than with ordinary sulphonated melamine admixtures. - Improved cohesion and particle dispersion minimizes segregation and bleeding and improve pumpability. - Chloride free, safe for use in prestressed and reinforced concrete. - Brand: Fosroc - Technical datasheet available on request.
