Novel grouting reinforcement material as well as preparation method and application thereof
The invention discloses a novel grouting reinforcement material as well as a preparation method and application thereof. The grouting reinforcement material is prepared by uniformly mixing the following raw materials in parts by mass: 450-480 parts of ordinary Portland cement, 40-45 parts of micro-expansive cement, 25-33 parts of silica fume, 90-110 parts of fly ash, 90-130 parts of composite steel mineral powder, 150-180 parts of steel slag sand, 25-35 parts of a water reducing agent, 0.1-0.3 part of an expanding agent, 0.05-0.08 part of cellulose ether, 0.1-0.2 part of a defoaming agent and1-2.5 parts of lithium carbonate; wherein the mass ratio of the mixed water to the mixed powder material is 0.16 to 0.21.
本发明公开了一种新型注浆加固材料及其制备方法和应用，该注浆加固材料由以下质量份数的各原料混匀后与水拌和而成：普通硅酸盐水泥450～480份，微膨胀水泥40～45份，硅灰25～33份，粉煤灰90～110份，复合钢矿粉90～130份，钢渣砂150～180份；减水剂25～35份，膨胀剂0.1～0.3份、纤维素醚0.05～0.08份、消泡剂0.1～0.2份和碳酸锂1～2.5份；其中，拌和的水与混合后的粉体材料的质量比为0.16～0.21。
