Micro-fine Cement Grout Material DMFC-GM-800/600
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㎡/㎏, the average grain size is below 5μm;
● 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;
