Shrinkage-compensating cement-based LS-1 grouting material and preparation method thereof
The invention discloses a shrinkage-compensating cement-based LS-1 grouting material and a preparation method thereof, and belongs to the technical field of cement-based grouting materials. The shrinkage-compensating cement-based LS-1 grouting material is prepared from, by mass, 85 to 95 parts of superfine Portland cement, 5 to 15 parts of a U-shaped expanding agent, 40 to 200 parts of water, a polycarboxylic acid high-efficiency PC water reducing agent accounting for 0.1-1.5% of the mass of the superfine Portland cement, an EHD early strength agent accounting for 0.1-1.5% of the mass of the superfine Portland cement, and gelatin accounting for 0.25-1.5% of the total mass of the solid material. The cement-based grouting material which is wide in source, low in price, non-toxic and micro-expansive is obtained by blending the superfine Portland cement, the polycarboxylic acid high-efficiency PC water reducing agent, the EHD early strength agent, the UEA expanding agent, the gelatin and the water according to a scientific ratio, the problem of cement shrinkage can be solved, and the grouting reinforcement effect on fractured surrounding rock can be improved.
一种补偿收缩的水泥基LS‑1注浆材料及其制备方法，属于水泥基注浆材料技术领域。其原料如下：超细硅酸盐水泥、聚羧酸高效PC减水剂、EHD早强剂、U型膨胀剂、明胶和水，其中超细硅酸盐水泥质量份数为85~95份，U型膨胀剂质量份数为5~15份，水质量份数为40~200份，聚羧酸高效PC减水剂占超细硅酸盐水泥质量的0.1~1.5%，EHD早强剂占超细硅酸盐水泥质量的0.1~1.5%，明胶占固料总质量的0.25~1.5%。本发明通过科学配比，通过将超细硅酸盐水泥、聚羧酸高效PC减水剂、EHD早强剂、UEA膨胀剂、明胶和水进行拌和，得到一种来源广、价格低、无毒害、微膨胀的水泥基注浆材料，能够解决水泥收缩问题并提升对裂隙围岩的注浆加固效果。
