摘要
本文通过尾矿砂取代河砂,研究尾矿砂对混凝土工作性能及强度的影响。结果表明,在混凝土中加入尾矿砂后,需要增加外加剂掺量,工作性虽略有下降,但不影响混凝土强度发展。
The effect of tailings sand on performance and strength of concrete is investigated by tailing sand replacing river sand in the paper.The results show that the adding tailing sand besides increasing admixture content decreases the performance of concrete but doesn't affect the strength of concrete.
