Micro-Fine Cement Grout Material

Description: the micro-fine cement grout is a new generation of rigid inorganic grouting material. It composed of high strength micro-fine cement, expander and vulcanizing agent.
Merit:
Non-toxic, odourless, pollution-free to groundwater and environment;
No shrinkage phenomenon happens when solidifing;
High fluidity, and the specific surface area is above 800©o/©k, the average grain size is below 5¦ìm;
Clotting time: can be regulated according to project need.
Be applicable to:
Cracks grouting of the dam and the dam foundation in hydraulic project ;
Pouring underground waterproof curtain;
Reinforcement of foundation settlement in highways, bridges and airport runways;
