Heavy metal polluted soil solidification and stabilization material, preparation method and application
The invention provides a heavy metal polluted soil solidification and stabilization material, a preparation method and application, and belongs to the field of solid waste resource utilization and environmental governance. According to the curing and stabilizing material, carbide slag micro-powder, waste glass micro-powder, coal gasification slag micro-powder, a polycarboxylic acid water reducer and fibers are used, and the mixing ratio of all the raw materials is adjusted, so that all the raw materials jointly play a role, and an alkali-activated cementing material with a three-dimensional latticed internal structure is formed; heavy metal ions are fixed through physical wrapping, adsorption and other effects on the heavy metal polluted soil, mineral activity of the mixture is excited only through reaction among solid wastes, and the material has gelling performance, saves cost, saves energy, is environmentally friendly and is convenient to construct. And meanwhile, the fiber is added, so that the freeze-thaw resistance of the solidified and stabilized heavy metal polluted soil can be effectively improved, and a better solidification and stabilization effect can be provided.
本发明提供了一种重金属污染土固化稳定化材料、制备方法及应用，属于固体废物资源化利用和环境治理领域。所述固化稳定化材料使用电石渣微粉、废玻璃微粉、煤气化渣微粉、聚羧酸减水剂和纤维，通过调配各原料之间的配合比，使得各原料共同发挥效用，形成具有三维网格状内部结构的碱激发胶凝材料，对重金属污染土通过物理包裹、吸附等作用使重金属离子固定，仅通过固体废弃物之间的反应激发混合料的矿物活性，使材料具有胶凝性，节约成本，节能环保，且施工便捷。同时，加入纤维可以有效提高固化稳定化重金属污染土的抗冻融性，能提供更好的固化稳定化效果。
