Why to their compact and high strength grouting material using grouting material to solve the crack problem

High strength grouting material high strength grouting material features high strength grouting material has good liquidity, early strength, high strength, no shrinkage, high bonding strength and micro expansion, good durability, not aging, no rust, oil resistance and other properties. 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 grouting material has the function of their flow, so that they can have good liquidity and their compact. Using grouting solve the problem of fracture grouting material is now widely used in our life, it brought very to the many plants are rich in nutrition. 1, construction water ash is bigger, cause local size is too large, aggregate, there is almost no such cracks caused by the need to cut, paste part to die, with big fluidity grouting material for filling water, with common grouting material is not suitable at this moment, must use adhesive ability is stronger, aggregate fine large flow grouting material. 2, micro cracks caused by exterior temperature difference with the pure water mud mixed building glue 1:2 brush interface. Basically is ok. As for the other cracks, depends on what the nature of the search for a solution to.
