Composite curing agent for curing soft soil by using carbide slag and caustic soda flakes as excitants and curing method thereof
The invention discloses a composite curing agent for curing soft soil by using carbide slag and caustic soda flakes as excitants and a curing method thereof, and belongs to the technical field of sludge curing. The composite curing agent is formed by mixing a composite alkali activator, a precursor and water, the mass of the precursor accounts for 41.7%-58.3% of the mass of the composite alkali activator, and the content of the water in the composite curing agent accounts for 50%-70% of the sum of the mass of the precursor and the mass of the carbide slag. The composite alkali activator is formed by mixing carbide slag and caustic soda flakes according to a mass part ratio of (4-6): 1, and the precursor is formed by mixing fly ash and slag according to a mass part ratio of 1: (4-6). The curing method comprises the step of directly and uniformly stirring the fly ash, the slag, the carbide slag and the caustic soda flakes according to the proportion. The main material of the curing agent is bulk solid waste, the characteristics of the bulk solid waste can be fully utilized, and the curing agent has the characteristics of low energy consumption, low emission, environmental friendliness and the like. When the curing agent is used for curing soft soil, the construction method is simple, the cost is low, the cured soil strength is high, and the environment-friendly benefit and the social benefit are remarkable.
一种以电石渣与片碱作为激发剂固化软土的复合型固化剂及其固化方法，属于淤泥固化技术领域。复合型固化剂由复合碱激发剂、前驱体、水，由三者拌合而成，其中前驱体质量占复合碱激发剂质量的41.7％‑58.3％，复合型固化剂中水的含量为前驱体和电石渣质量之和的50％‑70％。所述复合碱激发剂由电石渣和片碱按4～6：1的质量份数混合而成，前驱体由粉煤灰与矿渣按1：4～6的质量份数混合而成。固化方法为将粉煤灰、矿渣、电石渣、片碱固体按配比直接淤泥软土搅拌均匀即可。本发明固化剂主要材料为大宗固体废弃物，能够充分利用大宗固体废弃物特性，具有能耗低、排放小、环境友好等特点。采用本发明固化剂固化软土，具有施工方法简单，成本低，固化土强度高，环保效益和社会效益显著。
