Inorganic grouting material based on coal gangue as well as preparation method and application of inorganic grouting material
The invention relates to the technical field of grouting materials, and particularly discloses an inorganic grouting material based on coal gangue and a preparation method and application thereof, the inorganic grouting material comprises the following raw materials by weight: 35-45 parts of coal gangue, 4-6 parts of steel slag, 10-20 parts of gasification slag, 5-10 parts of a composite activator, 10-20 parts of cement, 1-4 parts of gypsum, and 2-6 parts of alumina; wherein the composite exciting agent is prepared from sodium silicate, sodium sulfate, sodium carbonate and sodium hydroxide according to the weight ratio of (1-3): (1-4): (1-3): (1-4). The inorganic grouting material can be used for backfilling of a coal mine goaf, blocking of underground water flow in deep foundation engineering, foundation reinforcement of large or high-rise buildings and grouting reinforcement of road foundations, and has the advantages of being high in structural strength, good in groutability, good in stability, free of segregation and water seepage, good in fluidity, low in cost and high in waste utilization rate.
本申请涉及注浆材料的技术领域，具体公开了一种基于煤矸石的无机注浆料及其制备方法和应用，所述无机注浆料包括以下重量份数的原料：煤矸石35‑45份，钢渣4‑6份，气化炉渣10‑20份，复合激发剂5‑10份，水泥10‑20份，石膏1‑4份，矾土2‑6份；其中，所述复合激发剂为硅酸钠、硫酸钠、碳酸钠、氢氧化钠按照1‑3:1‑4:1‑3:1‑4的重量比配置而成。本申请的无机注浆料可用于煤矿采空区的回填、深基础工程封堵地下水流、大型或高层建筑物的地基加固、道路基础的灌浆加固，其具有结构强度高，可注性好，稳定性好，不离析，不沁水，流动性好，成本低，高利废率的优点。
