Fosroc Limited Underwater (Anti-washout) Grout Admixture Cebex 250

Cebex 250 underwater grouting admixture is supplied as a ready to use, chloride-free white powder. When added to the grout, the Cebex 250 produces a gel in the water phase which surrounds the cement particles and protects them from washout. Cement hydration is not impaired by the use of this admixture. The addition of Cebex 250 may appear to thicken the grout, but this product forms a lubricating layer between the cement particles, thus improving the overall pumping ability of the grout.
