Method for preparing green cementing material through multi-waste synergistic recycling and green cementing material
The invention provides a method for preparing a green cementing material through multi-waste synergetic recycling and the green cementing material. The green cementing material is prepared from the following raw materials in parts by mass: 1-10 parts of sodium silicate, 1-10 parts of sodium silicate and 1-10 parts of sodium silicate. Comprising the following components in parts by weight: 30.0 to 50.0 parts of calcium-based active mineral powder, 10.0 to 20.0 parts of desulfurized gypsum, 10.0 to 20.0 parts of silicon-aluminum-based waste residue, 20.0 to 40.0 parts of active hydraulic gel, 1.0 to 2.0 parts of a first modifier and 3.0 to 6.0 parts of a second modifier. The preparation method comprises the following preparation steps: mixing the calcium-based waste residue and the silicon-aluminum-based waste residue, calcining, grinding to obtain an active hydraulic gel, mixing the active hydraulic gel with the active mineral powder and the desulfurized gypsum powder, adding the naphthalene sulfonate and the clay mineral powder, and carrying out rotary stirring to obtain the green cementing material without an exciting agent. The green cementing material prepared by the preparation method disclosed by the invention has a good curing effect on to-be-cured soft soil such as sludge, has good curing and eliminating effects on heavy metals and stink in the soft soil such as the sludge, and has obvious advantages compared with similar products.
本申请提供了一种多废协同资源化制备绿色胶凝材料的方法及绿色胶凝材料，其绿色凝胶材料原料按质量份数计，包括以下组分：30.0～50.0份的钙基活性矿粉、10.0～20.0份的脱硫石膏、10.0～20.0份的硅铝基废渣、20.0～40.0份的活性水硬性胶凝物、1.0～2.0份的第一改性剂以及3.0～6.0份的第二改性剂。其制备方法包括以下制备步骤：将钙基废渣、硅铝基废渣混合后经煅烧、研磨得到活性水硬性胶凝物，与活性矿粉、脱硫石膏粉混合，加入萘系磺酸盐、粘土矿粉旋转搅拌，无需激发剂即可制得绿色胶凝材料。本申请的制备方法制备的绿色胶凝材料对待固化的淤泥等软质土壤具有良好的固化作用，对淤泥等软质土壤中的重金属、恶臭具有良好固化和消除作用，相比同类产品有明显优势。
