Cement-based reinforcing grouting material with strong acid resistance
The invention provides a cement-based reinforcing grouting material with strong acid resistance. The material comprises components in parts by mass as follows: 100 parts of cement, 0-50 parts of an admixture, 20-30 parts of acid-resistant rubber powder, 3-10 parts of a water reducer, 200-300 parts of aggregate, 10-20 parts of an expanding agent and 0-0.5 parts of a water retaining agent, wherein the cement is Portland cement not lower than 42.5 level, the admixture is a mixture formed by mixing silica fume, fly ash and mineral powder in any proportion, the acid-resistant rubber powder is a mixture formed by mixing cinnamic acid, modified neoprene and vinyl acetate-neoprene copolymerized latex powder, the water reducer is a naphthalene water reducer or a polycarboxylate water reducer, the aggregate is machine-made sand, quartz sand or rubble. The material has the strong acid resistance and has advantages of self-compaction, micro-expansion, high early and later strength, construction convenience and the like of the cement-based reinforcing grouting material.
