摘要
近年来随着国家工程建设的逐渐增多,天然砂资源日益紧缺。尾矿细砂作为一种工业固体废弃物,污染环境、占用土地,而且存在安全隐患。尾矿细砂用于砂浆可以很好解决以上问题。试验结果表明,当尾矿细砂掺量在70%,适宜的外加剂掺量可以保证砂浆具有良好的性能。
Recently,with the increasing of national construction,naturals and resourceis in the face of short age increasingly.Fine tailings and as a kind of industrial solid waste,it not only polluted the environment,occupied land,but also has hidden trouble in safety.Experiment showed that when mix amount of fine tailing sand was under 70%,suitable amount of admixture could guarantee the good performance of mortar.
