Controllable low-strength material and preparation method thereof
The invention provides a controllable low-strength material and a preparation method thereof, the controllable low-strength material comprises the following raw materials: a solid raw material, an alkaline activator and water, the mass of the alkaline activator accounts for 1-5% of the mass of the solid raw material, and the mass of the water accounts for 30-40% of the mass of the solid raw material; the solid raw material specifically comprises the following components in parts by weight: 60-75 parts of waste incineration bottom slag; 10 to 20 parts of fly ash; 5-15 parts of granulated blast furnace slag powder; and 5-10 parts of slaked lime powder. According to the invention, the waste incineration bottom slag is used as a basic raw material and is uniformly mixed with the fly ash, the granulated blast furnace slag powder, the slaked lime powder, the alkaline activator and the water, all the raw materials play roles together, and the self-leveling, self-compacting and strength-controllable backfill material is prepared; the method solves the problems of insufficient utilization and insufficient consumption of the waste incineration bottom slag in the prior art, and develops a new field for resource utilization of the waste incineration bottom slag.
本申请提供一种可控性低强度材料及其制备方法，可控性低强度材料的原料包括固体原料、碱性激发剂和水，碱性激发剂的质量占所述固体原料质量的百分比为1～5％，水的质量占所述固体原料质量的百分比为30～40％；所述固体原料具体包括以下重量份组分：垃圾焚烧底渣60～75份；粉煤灰10～20份；粒化高炉矿渣粉5～15份；熟石灰粉5～10份。本申请以垃圾焚烧底渣为基础原料，将其与粉煤灰、粒化高炉矿渣粉、熟石灰粉、碱性激发剂和水均匀混合，各原料共同发挥效用，制备出了自流平、自密实、强度可控的回填材料，本申请解决了现有技术中存在的垃圾焚烧底渣利用不充分、消耗不足的问题，为垃圾焚烧底渣资源化利用开拓了新的领域。
