Method for preparing geopolymer-based recycled aggregate from micro-fine particle copper tailings
The invention discloses a method for preparing geopolymer-based recycled aggregate from micro-fine particle copper tailings. The invention relates to the technical field of harmlessness, reduction, recycling and comprehensive utilization of industrial solid waste (copper tailings). According to the method, raw materials comprise, by mass, 65 to 80 percent of copper tailings, 5 to 10 percent of flyash, 10 to 20 percent of water glass, 2 to 5 percent of NaOH and 0.5 to 1 percent of CaO. According to the method, the micro-fine particle copper tailings which are difficult to use are fully utilized, emission of solid waste is reduced, the micro-fine particle copper tailing absorption efficiency is high, and the prepared recycled aggregate is good in mechanical property.
本发明公开了一种微细粒铜尾矿制备地聚物基再生骨料的方法，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，该微细粒铜尾矿制备地聚物基再生骨料的方法按照质量百分比计，其原料组成包括：铜尾矿65‑80％，粉煤灰5‑10％，水玻璃10‑20％，NaOH 2‑5％，CaO 0.5‑1％。本发明提供了的微细粒铜尾矿制备地聚物基再生骨料的方法，充分利用难利用的细粒尾矿，减少固体废弃物的排放，消纳微细粒铜尾矿效率高，制备的再生骨料机械性能好。
