Method for preparing cement-based recycled aggregate from fine-grain copper tailings
The invention discloses a method for preparing cement-based recycled aggregate from fine-grain copper tailings, and relates to the technical field of harmlessness, reduction, recycling and comprehensive utilization of industrial solid waste (copper tailings). The method comprises a step of preparing following components in percentage by weight: 68-85% of fine-grain copper tailings, 5-15% of yellowsand, 8-15% of PC325R cement, 2% of gypsum and triethanolamine accounting for 0.01% of cement. Fine-grain tailings difficult to use are fully utilized, and emission of solid waste is reduced. The recycled aggregate is high in compressive strength, low in crushing value, economical, feasible, simple and convenient to operate and easy to obtain.
本发明公开了一种细粒铜尾矿制备水泥基再生骨料的方法，涉及工业固体废弃物(铜尾矿)无害化、减量化、资源化与综合利用技术领域，该细粒铜尾矿制备水泥基再生骨料的方法包括：按照质量百分比计的微细粒铜尾矿68‑85％，黄砂5‑15％，PC325R水泥8‑15％，石膏2％，以及质量占水泥用量0.01％的三乙醇胺。本发明充分利用难利用的细粒尾矿，减少固体废弃物的排放；通过本发明制备的再生骨料抗压强度高，压碎值低，且经济可行，操作简便易得。
