Fosroc Limited Underwater Concrete Admixture Conplast UW

Conplast UW underwater concrete admixture is a chloride free blend of selected polymers supplied as a fine brown powder. When added to concrete, Conplast UW produces a gel in the water phase which surrounds the cement particles and other fine components of the concrete mix and protects them from excessive washout both during placement and once the concrete is finally in position. Unlike other antiwashout materials, Conplast UW also contains plasticising agents which counteract the effects of the increased cohesion necessary to minimise washout and allow normal workability levels to be maintained without the addition of extra water. Conplast UW provides a degree of retardation to the concrete mix, allows longer journey times from batching to placement and better control of the placing process.
