How to improve the performance of grouting material - Hefei concrete grouting LiaoChang

grouting instructions no shrinkage grouting material grouting material series as grouting material chemical and beautiful seam an agent, and the widespread use of superfine mineral admixture, the mix proportion design of our country existing reinforced grouting material specification already cannot satisfy the high performance grouting material configuration and the construction of the practical need of. On the premise of guarantee strength of grouting reinforcement material requirements, selecting high quality admixture, maximum limit reduce the dosage of cement, is the effective way to improve reinforcement grouting material of many properties, and high strength grouting grouting material side need to anhui grouting material mortar grouting material unit key research and solve the issue.     1. Ratio of the consideration of & # 8195;   Traditional matching method based on workability, durability, etc to the ratio of grouting reinforcement material, so the grouting reinforcement material for configuration of liquidity will use more water, has a high relative cement dosage. The reinforcement ratio of grouting material, is faced with large deformation.     2. Mineral powder & # 8195;   The mixed mineral segment can replace part of cement and reduce the hydration heat, but also can reduce the dosage of cement threat to drying shrinkage. As a result of the mineral segment than cement fineness of fine, can improve the plastic viscosity of grouting material after China's entry into wto. Improving the compactness of grouting material and improve material with weak interface, to improve the durability of grouting material. ​ ​
