Steel slag-cyaniding tailing cementing material as well as preparation method and application thereof
The invention provides a steel slag cyaniding tailing cementing material as well as a preparation method and an application thereof. The steel slag cyaniding tailing cementing material is prepared from the following substances in percentage by mass: 30 to 60 percent of iron-selecting waste slag, 10 to 20 percent of aerated concrete waste, 15 to 25 percent of carbide slag and 10 to 30 percent of desulfurized gypsum. The method comprises the following steps: calcining the carbide slag, naturally cooling, and grinding; crushing, drying and grinding the aerated concrete waste; and grinding the desulfurized gypsum, and mixing the ground desulfurized gypsum with the iron separation waste residues of the steel slag cyaniding tailings in proportion to prepare the steel slag cyaniding tailing cementing material; and mixing the cementing material with Portland cement to prepare the steel slag cyaniding tailing cement. The preparation method disclosed by the invention is simple and easy to implement, can realize the synergistic utilization of various wastes, improves the additional value of the wastes, reduces the production cost of the cement, and has good social and economic effects.
本发明提出一种钢渣‑氰化尾渣胶凝材料及其制备方法和应用。所述钢渣‑氰化尾渣胶凝材料，由以下质量百分比的各物质组成：选铁废渣30～60％，加气混凝土废料10～20％，电石渣15～25％，脱硫石膏10～30％。将电石渣煅烧，自然冷却后，粉磨；加气混凝土废料破碎、烘干、粉磨；脱硫石膏粉磨后与钢渣‑氰化尾渣的选铁废渣按比例混合，制备得到钢渣‑氰化尾渣胶凝材料。将该胶凝材料和硅酸盐水泥混合，制备得到钢渣‑氰化尾渣水泥。本发明的制备方法简单、易行，可实现多种废弃物的协同利用，提高废弃物的附加值，降低水泥生产成本，具有很好的社会经济效应。
