摘要
随着矿山的不断开发,尾矿长期堆积,危害自然环境,需合理利用。本文通过测定利用金矿尾矿制备的砂浆的各项基本性能,对金矿尾矿制备新型砂浆进行试验研究。研究结果表明:在灰砂比为1∶3和1∶4时可分别制备出M20和M15的砂浆,该砂浆的各项性能与相同配合比下的天然砂浆最为接近,尾矿对强度和收缩性的影响较小。
Tailings are long-timely accumulated with continuous exploitation of mine and endanger the natural environment,which need to be reused reasonably.Experiments of making new type mortar with tailings of gold mines are researched through testing the basic performance of the new mortar.The results show that,the M20 and M15 mortar could be made when the c/s ratio is 1∶ 3 and 1∶ 4 respectively,which has the closest performance with natural mortar.Tailings have less influence to strength and shrinkage ratio.
