Magnesium acrylate-superfine cement double-liquid composite grouting material
The invention discloses a magnesium acrylate-superfine cement double-liquid composite grouting material. The main ingredients of the grouting material include a component A and a component B, wherein the component A comprises superfine cement, water, active magnesium oxide, a powdery naphthalene-based high-effect water reducer and silicon powder at the ratio of 100 to (50-100) to (0-5) to (0.5-1.5) to (2-5); and a component B comprises a magnesium acrylate solution with the concentration of 36-40 percent, calcium chloride, triethanolamine and sodium persulfate at the ration of (10-30) to (0.5-3) to (0.1-0.5) to (0.01-0.05). The grouting material provided by the invention is a composite grouting material consisting of a polymer and superfine cement, has the advantages of good groutability, adjustable setting time, high grout consolidation strength and the like, and has wide applicable prospect in the fields of broken and loose formation, foundation improvement, building foundation reinforcement and the like.
