Fosroc 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. Main uses: - Increases internal cohesion of the concrete mix, reducing the tendency of cement and other particles to be washed out of the concrete mix during placement - Facilitates the placement of concrete underwater by normal methods such as tremie pipe delivery - Once placed, concrete is more resistant to the action of moving water - Allows the production of higher quality and higher strength concrete underwater - Contains workability and setting control agents to assist in providing the levels of workability and working life necessary to allow control of placing Advantages: - Increases internal cohesion of the concrete mix, reducing the tendency of cement and other particles to be washed out of the concrete mix during placement - Facilitates the placement of concrete underwater by normal methods such as tremie pipe delivery - Once placed, concrete is more resistant to the action of moving water - Allows the production of higher quality and higher strength concrete underwater - Contains workability and setting control agents to assist in providing the levels of workability and working life necessary to allow control of placing - Brand: Fosroc - Technical datasheet available on request.
