Novel collapsible loess curing agent and preparation and application thereof
The invention relates to the technical field of soil solidification, and discloses a novel collapsible loess curing agent and preparation and application thereof, the collapsible loess curing agent comprises a dry blend, a mixed solution and an additive; wherein the dry blend comprises fly ash, cement and activated coal gangue powder; the mixed solution comprises solid sodium silicate, a water reducing agent and water; the additive is gypsum; the mass ratio of the fly ash to the cement to the activated coal gangue powder is (5-6): 2: 2. The cured loess prepared by the novel collapsible loess curing agent disclosed by the invention has excellent strength and stability, the preparation process is simple, the operation is convenient, and the production efficiency is greatly improved; meanwhile, the coal ash and the coal gangue adopted in the invention are both recycled solid wastes, so that resource reutilization is realized.
本发明涉及土壤固化技术领域，公开了一种新型湿陷性黄土固化剂及其制备和应用，该湿陷性黄土固化剂包括干混料、混合溶液和外加剂；其中，所述干混料包括粉煤灰、水泥和活化煤矸石粉；所述混合溶液包括固体硅酸钠、减水剂和水；所述外加剂为石膏；所述粉煤灰、水泥和活化煤矸石粉的质量比为5‑6：2：2。本发明所公开的新型湿陷性黄土固化剂所制备的固化黄土，具备出色的强度和稳定性，其制备流程简洁，操作便利，大幅提升了生产效率；同时，本发明采用的粉煤灰和煤矸石均为再生利用的固体废弃物，实现了资源化再利用。
