摘　　要：利用铜尾矿砂替代石英砂作为骨料制备水泥基灌浆料,以满足装配式建筑领域的需求。研究了铜尾矿砂替代率、灌浆料水灰比以及灰砂比对铜尾矿砂装配式建筑用灌浆料性能的影响。研究结果表明:水灰质量比0.29,灰砂质量比0.9,铜尾矿砂代替率70%时,添加适当的化学助剂,铜尾矿砂灌浆料的流动度、强度、膨胀率等均满足JG/T 408—2019的各项性能要求,尾矿砂的使用降低了灌浆料的生产成本。The paper utilizes the copper tailing soil to replace the quartz sand as the aggregate to make cement-based grout to meet the demands of the prefabricated buildings,researches the influences of the substitution rate of the copper tailing soil,the cement-water ratio,and cement-sand ratio on the performance of the copper tailing soil for high-strength grout of prefabricated buildings,and proves by the research result that the fluidity,strength and expansion rate of the copper tailing soil grout can averagely satisfy the demands of JG/T 408—2019,when the cement-water ratio is 0.29,the cement-sand ratio 0.9 and the substitution rate of the copper tailing soil 70%,so the usage of the tailing sand lowers the production cost of the grout.
