Method for preparing flow-state solidified soil by utilizing construction waste soil
The invention relates to the field of constructional engineering, in particular to a method for preparing flow-state solidified soil from construction waste soil. Comprising the following steps: preparing the admixture special for the flow-state solidified soil, and stirring the admixture with water and soil to form the flow-state solidified soil. Wherein the curing agent is prepared from the following components in percentage by weight: 30 to 35 percent of fly ash, 25 to 30 percent of slag, 10 to 15 percent of quick lime, 15 to 20 percent of calcined kaolin, 2 to 5 percent of sodium silicate, 1 to 3 percent of sodium sulfate and 1 to 2 percent of polyether organic silicon defoaming agent. When 5-10% by weight of the curing agent is stirred with building residue soil and water to form slurry, direct backfilling can be achieved, vibration is not needed, construction is simple, the construction period is short, and the construction period is only one tenth of that of common tamping backfilling. The strength and water resistance are superior to those of a foamed concrete backfilling process, and the cost is saved by 30-50% compared with that of foamed concrete backfilling. Compared with similar products, the concrete has the characteristics of low cost, high strength, better impermeability and the like.
本发明涉及建筑工程领域，尤其涉及一种利用建筑渣土制备流态固化土的方法。包括流态固化土专用外加剂的制备及与水、泥土搅拌成流态固化土的制备方法。其中所用固化剂按重量计，由下列成分组成：粉煤灰30‑35%、矿渣25‑30%、生石灰10‑15%、煅烧高岭土15‑20%、硅酸钠2‑5%、硫酸钠1‑3%、聚醚有机硅消泡剂1‑2%。使用本发明的固化剂5‑10%重量份与建筑渣土、水搅拌成浆，可以直接回填，不需要振捣，施工简单，工期短，工期仅是普通夯实回填十分之一。强度和耐水性优于发泡混凝土回填工艺，成本相对发泡混凝土回填节省30‑50%。相对同类产品本发明具有成本低廉、强度高、抗渗能力更好等特点。
