摘　　要：以某冶炼厂废水处理渣、水泥、粗骨料和细骨料为原料,进行混凝土制备试验研究。结果表明,在水胶比为40%、砂率为29%、废水处理渣为15%的条件下,可得到28d抗压强度大于C15的混凝土。在满足普通混凝土强度要求的前提下,所制备的混凝土浸出液中,重金属含量均达到GB 5085—1996《危险废物鉴别标准》的要求,无二次污染。The preparation of concrete with the raw materials of sewage treatment residues from a smelting plant, cement, coarse aggre- gate and fine aggregate was experimented.The results show that the concrete with the 28d compressive strength greater than C15 can be obtained, when the water - binder ratio is 40%, the sand ratio is 29%, and the sewage treatment residues is 15%. On the promise of satis- fying the requirements of ordinary concrete strength,the contents of heavy metals in the leaching solution of the prepared concrete can meet the requirements in the ＂Identification Standard for Hazardous Wastes＂ （GB 5085-1996 ）, and will not cause secondary pollu- tion.
