FOSROC CONPLAST SP430 (20L)

Conplast SP430 is Naphthalene based admixture with selected materials. It disperses the fine particles in the concrete mix, enabling the water content of the concrete to perform more effectively. The very high levels of water reduction possible allow major increases in strength to be obtained 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. 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 without excessive cement contents. Use in production of flowing concrete permits easier construction labour costs without increasing water contents. Improved cohesion and particle dispersion minimizes segregation and bleeding and improves pump ability.
