High-flowability and high-water-retention deep well mudstone grouting anti-seepage reinforcement material and preparation method thereof
The invention discloses a high-flowability and high-water-retention deep well mudstone grouting anti-seepage reinforcement material and a preparation method, belongs to the technical field of grouting materials, and is particularly suitable for deep roadway fractured rock mass grouting anti-seepage reinforcement. The concrete is prepared from the following components in parts by weight: 55 to 65 parts of Portland cement, 10 to 25 parts of sulphoaluminate cement, 7 to 20 parts of mineral powder, 1 to 5 parts of fly ash, 1 to 5 parts of gypsum, 28 to 30 parts of water, 0.82 to 1.2 parts of a water reducing agent, 0.03 to 0.044 part of hydroxypropyl methyl cellulose, 0.005 to 0.012 part of sodium polyacrylate, 0.01 to 0.012 part of sodium alginate and 0.52 to 0.72 part of nano silica sol. 0.38 to 0.56 part by weight of lithium carbonate, 0.06 to 0.088 part by weight of a plastic expanding agent and 0.18 to 0.26 part by weight of a defoaming agent. The gel has the advantages of controllable gelation time, high flowability, high water retention, micro-expansion, high early strength, high strength and low cost.
本发明公开一种高流动高保水的深井泥岩注浆防渗加固材料及调配方法，属于注浆材料技术领域，尤其适用于深部巷道裂隙岩体注浆防渗加固。组成为：硅酸盐水泥55～65重量份、硫铝酸盐水泥10～25重量份、矿粉7～20重量份、粉煤灰1～5重量份、石膏1～5重量份、水28～30重量份、减水剂0.82～1.2重量份、羟丙基甲基纤维素0.03～0.044重量份，聚丙烯酸钠0.005～0.012重量份、海藻酸钠0.01～0.012重量份、纳米硅溶胶0.52～0.72重量份，碳酸锂0.38～0.56重量份、塑性膨胀剂0.06～0.088重量份、消泡剂0.18～0.26重量份。其凝胶时间可控、高流动，高保水、微膨胀、高早强、高强度、成本低。
