Conplast SP430 is a chloride free, superplasticising
admixture based on selected sulphonated napthalene polymers. It is supplied as a brown solution which instantly disperses in water.
Conplast SP430 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
