Phosphogypsum engineering backfill material and backfill method
The invention relates to the technical field of ardealite solid waste recycling, in particular to an ardealite engineering backfill material and a backfill method, and the ardealite engineering backfill material is prepared from the following raw materials in percentage by mass: 89-95% of ardealite powder and 10-13% of a water-resistant curing agent. Wherein the water-resistant curing agent is prepared from the following raw materials in percentage by mass: 8%-23% of ash calcium powder, 1.5%-2.4% of a water repellent and 69%-83% of cement, and the backfilling method comprises the steps of pretreatment, layered backfilling, layered tamping, maintenance, protection and the like. The method can be widely applied to backfilling of mine pits or natural low-lying pits, resource utilization and popularization of industrial solid waste are achieved, the purpose of ecological restoration is achieved, and economic benefits and social benefits brought by the method are greatly improved.
本发明涉及磷石膏固废物再生利用技术领域，具体为一种磷石膏工程回填料及回填方法，磷石膏工程回填料按以下质量百分比的原材料制成：磷石膏粉：89％～95％、耐水固化剂：10％～13％。其中耐水固化剂按以下质量百分比的原材料制成：灰钙粉8％～23％、憎水剂1.5％～2.4％、水泥69％～83％，本发明回填方法按预处理、分层回填、分层夯实、养护和防护等步骤进行，本发明通过将工业副产品磷石膏改性所制成的材料，按照回填方法，可广泛应用于矿坑或天然低洼坑的回填，既实现了对工业固废的资源化利用和推广，又达到生态修复的目的，大幅提高其带来的经济效益和社会效益。
