High strength grouting material how to improve the durability performance - Henan grouting material manufacturers

High strength grouting material high strength grouting material standard specification, high strength grouting material detection based on henan high strength grouting material manufacturer & # 8195;   With high strength without shortening the grouting material chemistry and beautiful seam an agent and superfine mineral admixture in use, the existing of the henan high-strength infuse pulp latest standard specification size cooperation is higher than design specification has not satisfied function grouting material and equipment as well as the actual demand of the construction. In ensuring high strength grouting material strength requirements under the premise of reasonable selecting high quality admixture, maximum limit the decline of the dosage of cement, is the effective way to improve high strength grouting material of many functions, and high strength grouting material demand points for discussion and deal with the subject. ？ That how to improve the durability of high strength grouting material, China metallurgical construction institute to summarize several: the & # 8195;   1. Ratio of the consideration of the traditional matching method is a practical, durability and so on to consider the ratio of grouting material, and the grouting reinforcement materials to complete equipment of liquidity will choose more the amount of water, has a high relative cement dosage. The reinforcement ratio of grouting material, also face a greater risk of deformation.     2. The mixed mineral powder mineral segment can replace part of cement and reduce the hydration heat, and it also can cut the cement dosage on drying shrinkage of blackmail. Because of mineral segment than cement fineness of fine, attend to progress after high strength grouting material plastic viscosity. Then build progress in kunming the compactness of grouting materials, improve data with weak interface, the effect of the grouting material durability to progress.
