Roadbed soil curing agent, preparation method thereof and roadbed material containing roadbed soil curing agent
The invention discloses a roadbed soil curing agent, a preparation method thereof and a roadbed material containing the roadbed soil curing agent, and belongs to the technical field of soil curing agents. The curing agent is prepared from the following components in parts by weight: 40 to 50 parts of bentonite, 0.5 to 2.5 parts of hexadecyl trimethyl ammonium chloride, 40 to 50 parts of silicon dioxide, 20 to 30 parts of aluminum oxide, 6 to 10 parts of nano calcium carbonate, 1 to 3 parts of an ion complexing agent and 10 to 20 parts of a silane coupling agent. The silicon dioxide, the aluminum oxide and the hexadecyl trimethyl ammonium chloride can remarkably improve the water adsorption capacity of the bentonite on the surfaces of soil particles, so that the water stability and the strength of the roadbed material are remarkably improved. Under the interaction of all the components, the curing agent disclosed by the invention can reduce adsorbed water in soil, optimize the hydration performance of cement, and tightly bond soil particles together, so that the water stability and strength of the cured soil are synergistically enhanced.
本发明公开一种路基土固化剂及其制备方法、以及包含其的路基材料，属于土壤固化剂技术领域。所述固化剂包括以下重量份数的各组分：膨润土40～50份、十六烷基三甲基氯化铵0.5～2.5份、二氧化硅40～50份、氧化铝20～30份、纳米碳酸钙6～10份、离子络合剂1～3份、硅烷偶联剂10～20份。二氧化硅、氧化铝和十六烷基三甲基氯化铵可以显著提升膨润土释放土粒子表面吸附水的能力，进而显著提升路基材料的水稳定性和强度。本发明的固化剂在各组分的相互作用下，可以降低土壤中的吸附水，并优化水泥水化性能，将土壤颗粒紧密胶结在一起，协同增强了固化土的水稳定性和强度。
