Performance-controllable inorganic grouting material as well as preparation method and application thereof
The invention provides a performance-controllable inorganic grouting material as well as a preparation method and application thereof. The inorganic grouting material is prepared by mixing the following raw materials in parts by mass: 40-80 parts of cement; 5-40 parts of a functional admixture; 0-40 parts of industrial solid waste; 2-8 parts of a combined expanding agent; 0.1 to 1.5 parts of a water reducing agent; 0-1 part of biomass fiber; 0.01 to 3 parts of a reinforcing agent; 0.01 to 0.5 part of thickening time control agent; and 0.01 to 0.3 part of a modifier. According to the inorganic grouting material disclosed by the invention, various indexes such as strength, granularity and setting time can be controlled, and meanwhile, the inorganic grouting material is slightly expanded after being hardened and is excellent in durability. The performance-controllable inorganic grouting material disclosed by the invention can meet various grouting requirements of underground engineering grouting such as coal mines and tunnels, leakage and crack repair grouting, rock stratum and building foundation reinforcement grouting and the like. Meanwhile, industrial solid waste can be consumed, and energy conservation and environmental protection are achieved.
本发明提出一种性能可控的无机注浆材料及其制备方法、应用。该无机注浆材料由以下原料按质量比混合而成：水泥40~80份；功能型掺合料5~40份；工业固废0~40份；组合膨胀剂2~8份；减水剂0.1~1.5份；生物质纤维0~1份；增强剂0.01~3份；调凝剂0.01~0.5份；改性剂0.01~0.3份。发明公开的无机注浆材料，其强度、粒度、凝结时间等各项指标可控制，同时兼顾硬化后微膨胀、耐久性优。本发明公开的性能可控的无机注浆材料，可满足煤矿、隧道等地下工程注浆，渗漏、裂缝修复注浆，岩层、建筑地基加固注浆等多种注浆需求。同时能消纳工业固废，节能环保。
