Why can CGM high-strength grouting material gravity dense high strength

CGM high-strength grouting CGM high-strength grouting material price CGM high-strength grouting materials manufacturer CGM high-strength grouting materials have good liquidity, early strength, high strength, no shrinkage, high bond strength, micro expansion, good durability, not aging, no rust, oil resistance and other properties. CGM high-strength grouting material has the function of their dense because in the production of grouting materials, joined the efficient and beautiful seam an agent composition, plus the seam an agent the molecular structure of the comb, a more active group on the main chain, and the strong polarity, these groups have a sulfonic acid group and carboxylic acid groups, the hydroxyl groups, etc. Various groups on the effect of cement paste is different, good dispersion of the groups such as sulfonic acid, carboxylic acid groups in addition to good dispersibility, and retarding action, the hydroxyl groups have liquidity effects. In the early hydration of cement minerals c3a, c4af hydration of cement particle surface with positive charge, formed in the efficient and beautiful seam an agent molecular dissociation of sulfonic acid group and carboxylic acid groups such as the adsorption effect of anion is stronger, the negative ions on the surface of cement particles adsorption dominant, making the cement particles dispersion due to the effect of electrostatic repulsion, cement - — Water system in a stable dispersion state, there is the water after the CGM high-strength grouting material has the function of their flow so that they can have good liquidity and their compact.
