Grouting material for treating subsidence area
The invention relates to a grouting material for treating a subsidence area. The grouting material is prepared by uniformly mixing the following raw materials in percentage by mass: 20-45% of mineral powder particles, 5-10% of steel slag powder particles, 5-15% of Portland cement, 1-3% of anhydrous sodium sulphate, 5-25% of fly ash and 20-50% of construction waste aggregate, and drying the mixture until the water content is lower than 5%. The grouting material of the invention has the advantages of low cost and high early strength.
本发明涉及一种用于塌陷区治理的注浆材料，该注浆材料由下述质量百分比的原料混合均匀后，经烘干至含水率低于5%制得：矿粉微粒20~45%，钢渣粉微粒5%~10%，硅酸盐水泥5%~15%，元明粉1%~3%，粉煤灰5%~25%，建筑垃圾骨料20%~50%。本发明成本低、早期强度高。
