Preparation method of composite cementing filling material
The invention discloses a preparation method of a composite cemented filling material, and relates to the technical field of filling material preparation. Industrial solid waste red mud, iron tailing sand and waste oyster shells are mixed to prepare the filling material, the compressive strength of the filling material can reach 10 Mpa 28 days after backfilling, and the construction requirement is met; meanwhile, the slag is 0.0953 yuan/kg, the red mud is 0.08 yuan/kg, the iron tailing sand is 0.06 yuan/kg, the water is 0.004 yuan/kg, the oyster shells belong to industrial waste materials, and the raw material price of each cubic meter of the filling material is 87.1 yuan/m without considering the cost according to the filling material density of 1700 kg/m, so that the cost is remarkably reduced.
本发明公开了一种复合胶结填充材料的制备方法，涉及填充材料制备技术领域。本发明利用工业固体废料赤泥、铁尾矿砂、废弃牡蛎壳混合制成填充材料，该填充材料回填后28天抗压强度可达10Mpa，满足了施工要求；同时矿渣0.0953元/kg、赤泥0.08元/kg、铁尾矿砂0.06元/kg、水0.004元/kg、牡蛎壳属于工业废料，不计成本，按充填材料密度1700kg/m³计算，每立方米充填材料原材料价格为87.1元/m³，显著降低了成本。
