Alkali-activated solid waste-based backfill material and preparation method thereof
The invention discloses an alkali-activated solid waste-based backfill material. The backfill material comprises the following components: a solid waste-based composite material, an additive, sodium silicate and water, wherein the solid waste-based composite material comprises the following components: 60-75 parts of construction waste fine powder; 10 to 20 parts of calcined coal gangue micro powder; 5-10 parts of desulfurized gypsum powder; 5-15 parts of household garbage incineration ash micro powder; and 5-15 parts of caustic sludge. The mass of the sodium silicate accounts for 1-5% of the mass of the solid waste-based composite material; the mass of the water accounts for 20-30% of the mass of the solid waste-based composite material. The solid waste-based composite material is used as a basic raw material and is uniformly mixed with the additive, the sodium silicate and the water, all the raw materials jointly exert effects, the self-leveling and self-compacting backfill material with controllable strength and hardening time is prepared, the problems of insufficient utilization and insufficient consumption of solid wastes in the prior art are solved, and the backfill material is suitable for industrial production. And a new field is developed for resource utilization of solid wastes.
本发明公开了碱激发固废基回填材料，回填材料包括如下组分：固废基复合材料、外加剂、泡花碱和水；其中，固废基复合材料包括如下组分：建筑垃圾细粉60‑75份；煅烧煤矸石微粉10‑20份；脱硫石膏粉5‑10份；生活垃圾焚烧灰渣微粉5‑15份；碱渣5‑15份。泡花碱的质量占所述固废基复合材料质量的百分比为1‑5％；水的质量占所述固废基复合材料质量的百分比为20‑30％。本申请以固废基复合材料为基础原料，将其与外加剂、泡花碱和水均匀混合，各原料共同发挥效用，制备出了自流平、自密实、强度和硬化时间可控的回填材料，本申请解决了现有技术中存在的固体废弃物利用不充分、消耗不足的问题，为固体废弃物资源化利用开拓了新的领域。
