Broken rock stratum roadway wall thickness grouting material and preparation method thereof
The invention relates to a broken rock stratum roadway wall thickness grouting material, which is prepared from the following raw materials in percentage by mass: 50%-80% of S95 mineral powder, 1%-10%of anhydrous sodium sulphate, 5%-25% of sulphoaluminate cement clinker micro powder, 5%-20% of silicate cement clinker micro powder, 2%-10% of silicon powder and 0.1%-0.5% of a water reducing agent.The invention further discloses a preparation method of the grouting material. The grouting material has the advantages of high flowability, high early strength, short setting time and the like, can well reinforce the broken rock stratum roadway surrounding rock, effectively controls the large deformation of the roadway surrounding rock caused by rock stratum breakage, and obviously lowers the repair rate of the broken rock stratum roadway.
本发明涉及一种破碎岩层巷道壁厚注浆材料，该材料由下述质量百分比的原料制得：S95矿粉50%~80%，元明粉1%~10%，硫铝酸盐水泥熟料微粉5%~25%，硅酸盐水泥熟料微粉5%~20%，硅粉2%~10%，减水剂0.1%~0.5%。本发明还公开了该注浆材料的制备方法。本发明具有高流动性、早期强度高、凝结时间短等优点，能够很好地加固破碎岩层巷道围岩，有效控制因岩层破碎导致的巷道围岩大变形，并显著降低破碎岩层巷道的返修率。
