Grouting material for reinforcing broken roof
The invention relates to a grouting material for reinforcing a broken roof. The grouting material is prepared by mechanically stirring and mixing the following raw materials in percentage by weight for 20 minutes: 60%-80% of 425 Portland cement, 5%-25% of S95 mineral powder, 5%-10% of cement clinker, 3%-5% of desulfurized gypsum, 1%-3% of anhydrous sodium sulphate and 0.1%-0.5% of a water reducingagent. The grouting material is safe, pollution-free, low in cost and stable in performance, and can achieve the purposes of improving the rock mass condition of the broken roof and effectively reinforcing.
本发明涉及一种用于破碎顶板加固的注浆材料,该注浆材料由下述重量百分比的原料机械搅拌混合20分钟后制得:425硅酸盐水泥60%~80%,S95矿粉5%~25%,水泥熟料5%~10%,脱硫石膏3%~5%,元明粉1%~3%,减水剂0.1%~0.5%。本发明安全无污染、成本低、性能稳定,可起到改善破碎顶板岩体条件和有效加固的目的。
