Phosphogypsum-based backfill material and preparation method thereof
The invention discloses a phosphogypsum-based backfill material, which is prepared from the following raw materials in parts by weight: 0.2 to 0.8 part of water, 0.01 to 0.3 part of cement, 0.01 to 0.6 part of fly ash, 0 to 0.6 part of stone powder, 0 to 3 parts of sand and 0 to 5 parts of stone. And 1 part of any one or a combination of two or more of ardealite, modified ardealite and modified ardealite powder. And (0-0.5) parts of any one of basalt fiber, graphite and steel fiber. According to the method, the solid waste phosphogypsum-based material and the stone powder are utilized, so that the resource utilization rate is increased, the underground space, especially water pollution, is reduced, and the backfill detection cost is saved; the ardealite is utilized, so that the strength and the durability are improved, and cracking is avoided.
本发明公开了一种磷石膏基回填材料，按照重量份计包括如下原料：水0.2‑0.8份、水泥0.01‑0.3份、粉煤灰0.01‑0.6份、石粉0‑0.6份、砂0‑3份、石0‑5份；还包括：1份磷石膏、改性磷石膏、改性磷石膏粉中的任一种或两种及以上的组合；(0‑0.5)份的玄武岩纤维、石墨、钢纤维中的任一种。本发明利用了固废磷石膏基材料及石粉，提高资源利用率、减少地下空间尤其是水污染、节省了回填检测的成本；利用了磷石膏，提高了强度、耐久性能，不开裂。
