Cement-based grouting material prepared based on machine-made sand
The invention discloses a cement-based grouting material prepared based on machine-made sand. The cement-based grouting material is prepared from ordinary Portland cement, a polymer modified nano filler, an active admixture, the machine-made sand and an additive, the polymer comprises polyacrylamide modified by nano silicon dioxide aerogel and an EVA emulsion with the solid content of 55%; the nano filler is nano titanium dioxide; the active admixture comprises superfine fly ash, talcum powder and anhydrous calcium aluminum sulfate; the additive is prepared from a polycarboxylate water reducing agent, methyl cellulose, sodium citrate and polydimethylsiloxane. The grouting material provided by the invention is high in strength and good in stability.
本发明公开了一种基于机制砂制备的水泥基灌浆材料，包括普通硅酸盐水泥、聚合物改性纳米填料、活性掺合料、机制砂、外加剂；所述聚合物包括纳米二氧化硅气凝胶改性的聚丙烯酰胺和固含量为55％的EVA乳液；所述纳米填料为纳米二氧化钛；所述活性掺合料包括超细粉煤灰、滑石粉、无水硫酸铝钙；所述外加剂包括聚羧酸盐减水剂、甲基纤维素、柠檬酸钠、聚二甲基硅氧烷。本发明提供的灌浆材料强度大，稳定性好。
