Cement grouting material freezing-thawing resisting what do you mean

Cement-based grout CGM grout material, freezing-thawing resisting is what mean? Grouting material freezing-thawing resisting the request of the 200, 300, on behalf of what? Answer; Freezing-thawing resisting refers to the degree of intrusive grouting material antifreeze can! 200 showed that 200 times freeze-thaw cycle, 300 showed that 300 times of freeze-thaw cycle, grouting material specimen quality loss is not greater than 5%, moving die is not less than 60% in the second, how to increase the freezing-thawing resisting grouting material circulation, increase what information? 1, usually capable of water cement ratio of grouting material progress, frost resistance, because the water cement ratio is the main factor affecting the density of grouting material. 2, water reducing admixture seam an agent, especially the high efficiency water reducing the seam an agent. Water reducing beauty seam an agent is in grouting material slump under the same conditions, can cut the mixing effect and beautiful seam an agent. 3, mixing air-entraining beautiful seam an agent or type air-entraining water reducing beautiful seam grouting material antifreezing air-entraining agent progress in beauty seam an agent is mixed with grouting material, mixing can introduce a large number of uniform distribution of tiny air bubbles to improve grouting material blend of homework, and can save the tiny air bubbles in the hardening for improving freezing-thawing resisting durability of grouting materials plus the seam an agent. Many customers have thought that the summer heat just make necessary maintenance, this is wrong, freezing-thawing resisting the same cycle is very important.
