Multi-element solid waste soil stabilizer
The invention discloses a multi-element solid waste soil stabilizer which is prepared from the following raw materials: red mud, fly ash, desulfurized gypsum, lime and ordinary Portland cement. The soil stabilizer is high in solid waste mixing amount, specifically, the solid waste mixing amount is high in the preparation raw materials, the slag eating amount is large, and the accumulation cost ofthe solid waste and the influence on the environment are reduced. The strength of the soil stabilizer is high, specifically, the 7d unconfined compressive strength of stabilized soil solidified by theprepared multi-element solid waste soil stabilizer exceeds 4.2 MPa and can reach 8.1 MPa to the maximum extent, the requirement for the compression resistance of a highway subgrade with the cumulative standard axis number exceeding 12*10<6> in relevant national regulations is met, and the requirement for the compression resistance of a highway mainly used for heavy-load vehicles is partially met.The 28d compressive strength of the prepared multi-element solid waste soil stabilizer mortar exceeds 20MPa, and the highest 28d compressive strength can reach 35MPa or above. Compared with a traditional cement curing agent, the cost is saved by more than 40%. The use difficulty of the preparation machine is low.
本发明公开了一种多元固体废弃物土壤固化剂，由如下原料制成：赤泥，粉煤灰，脱硫石膏，石灰，普通硅酸盐水泥；本发明高固废掺量：制备原料中，固体废弃物掺量高，吃渣量大，减少固体废弃物的堆积成本和对环境造成的影响，高强度：所制备多元固体废弃物土壤固化剂固化的土壤稳定土7d无侧限抗压强度超过4.2MPa，最高可达8.1MPa，满足国家相关规定中累计标准轴次超过12×106的公路路基所需抗压性能需求，部分满足主要行驶重载车辆的公路所需抗压性能要求。所制备多元固体废弃物土壤固化剂胶砂28d抗压强度超过20MPa，最高可达35MPa以上。相比传统水泥固化剂，节省成本超过40％。制备机械使用难度低。
