Why high strength grouting material to their dense? - Anti-freezing type grouting material

High strength grouting material anti frozen type high strength grouting material high strength grouting material concrete secondary grouting material & # 8195;   Grouting material with high strength material as aggregate to cement as the seam an agent, complementary with high flow, micro expansion, made from materials such as anti segregation. It joined a certain amount of water in the construction site, use after stir well. Grouting material has good artesian, rapid hardening, early strength, high strength, no shrinkage, micro expansion; Nontoxic and harmless, not aging, on the water quality and the surrounding environment pollution-free, good tightness, rust etc.     Below, constant small make up to give you a brief introduction about why high strength grouting material to their dense? 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 sulfonated grouting material wholesale acid group, hubei 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 is in a state of stable dispersion, they appeared after the water filling propylene acid salt grouting material quotation slurry has the function of their flow, so that they can have good liquidity and their compact.
