摘要：利用水泥、粉煤灰和建筑垃圾再生过程中产生的筛底料制备了可控低强度回填材料，研究了灰砂比、粉砂比和水固比对回填材料流动性、抗压强度、应力-应变关系和承载力的影响。结果表明：回填材料的流动度与用水量有关，受灰砂比和粉砂比的影响较小；回填材料的抗压强度与灰砂比和水固比之间存在较好的幂指数关系；回填材料的承载力受灰砂比和浇筑龄期的影响较大，灰砂比越大，达到承载力要求所需的时间越短；控制水泥掺量在36~96 kg/m3之间时，可制备出后期可开挖性满足回填工程要求的回填材料。实际工程中，需根据工期和经济要求选择合理的水泥掺量。 Abstract: The controlled low-strength backfill material was prepared by using cement, fly ash and the screen bottom material produced in the recycling process of construction waste, and the effects of cement-sand ratio, fly ash-sand ratio and water-solid ratio on the fluidity, compressive strength, stress-strain relationship and bearing capacity of backfill materials were studied. The results show that the fluidity of backfill material is related to the water consumption, and is less affected by cement-sand ratio and fly ash-sand ratio. There is a good power exponent relationship between the compressive strength of backfill materials and the cement-sand ratio and water-solid ratio. The bearing capacity of backfill materials is greatly affected by the cement-sand ratio and pouring age, and the greater the cement-sand ratio, the shorter the time required to reach the bearing capacity requirements. When the cement consumption is controlled between 36~96 kg/m3, the backfill materials with later excavatability meeting the requirements of backfill engineering can be prepared. In actual projects, reasonable cement consumption should be selected according to the construction period and economic requirements.

Abstract: The controlled low-strength backfill material was prepared by using cement, fly ash and the screen bottom material produced in the recycling process of construction waste, and the effects of cement-sand ratio, fly ash-sand ratio and water-solid ratio on the fluidity, compressive strength, stress-strain relationship and bearing capacity of backfill materials were studied. The results show that the fluidity of backfill material is related to the water consumption, and is less affected by cement-sand ratio and fly ash-sand ratio. There is a good power exponent relationship between the compressive strength of backfill materials and the cement-sand ratio and water-solid ratio. The bearing capacity of backfill materials is greatly affected by the cement-sand ratio and pouring age, and the greater the cement-sand ratio, the shorter the time required to reach the bearing capacity requirements. When the cement consumption is controlled between 36~96 kg/m³, the backfill materials with later excavatability meeting the requirements of backfill engineering can be prepared. In actual projects, reasonable cement consumption should be selected according to the construction period and economic requirements.
