摘　　要：采用对比试验方法,对胶结充填材料抗压强度的影响因素进行了研究。研究结果表明:与对比样品相比,掺入复合胶凝材料、减水剂、矿物掺合料均能明显提高硬化试块的抗压强度,其原因是硬化体中孔径被细化。Study on influencing factors of the compressive strengths of low-strength cemented backfill was carried on.The results show that contrast the controlled samples, the compressive strength of low-strength cemented backfill samples with complex binder or water-reducing agent or mineral admixtures is obviously increased.The reason is that the pore access diameter in the samples were all refined.

关 键 词：低强度胶结充填材料 抗压强度 影响因素 压汞测孔法
