摘要:
建筑垃圾用作井下充填材料,不仅可以消除其大量堆放造成的环境危害,而且可以解决矿山采空区充填材料不足的问题,有效维护采场安全。采用土工试验的方法,测试了建筑垃圾的基本物理性质。针对建筑垃圾一次破碎中间粒径缺失问题,提出了新的破碎工艺,即将一次破碎后粗骨料的1/3二次破碎至15 mm以下后回混,能够得到级配良好的骨料。根据膏体材料强度及流动性能要求,选用建筑垃圾制备骨料,普通水泥作为胶凝材料,粉煤灰作为添加料,制备合格的膏体材料,开展单轴抗压试验和坍落度试验。结果表明:使用建筑垃圾制备骨料时,控制粉煤灰掺量为15%、水泥掺量为10%、含水率在27%~28%之间,膏体材料的坍落度为21.5~24.0 cm,得到的充填体3 d单轴抗压强度为1.23 MPa、28 d单轴抗压强度为3.55 MPa,能够满足膏体材料对强度和流动性能的要求。
