以尾矿砂取代天然砂配制了尾矿砂钢纤维喷射混凝土,并从粉煤灰掺量、硅粉掺量、钢纤维掺量三方面,对其力学性能进行了研究,试验结果表明:粉煤灰掺量为10%以及硅粉掺量为5%是尾矿砂钢纤维喷射混凝土的最优掺量。
The tailings sand steel fiber shotcrete was prepared by replacing the natural sand with tailings sand. The mechanical properties were studied from the aspects of fly ash content, silicon powder content and steel fiber content. The results showed that fly ash The optimal content of tailing sand steel fiber sprayed concrete is 10% and the content of silicon powder is 5%.
