摘　　要：我国建筑垃圾废弃物与日俱增,再生循环利用率不高;炉渣是生活垃圾焚烧最大产量二次固废,亟需资源化利用。围绕多源无机固废协同资源化目标,探究建筑垃圾和焚烧炉渣协同制备自密实回填料可行性。结果表明,建筑垃圾的添加能提升10%~25%自密实回填材料抗压性能;而炉渣的添加,能降低50%~75%的自密实回填材料抗压性能。利用两种物料特性,协同制备自密实回填材料,可实现炉渣和建筑垃圾添加比例达75%~85%,显著提升多源低值无机固废资源化利用率,推动我国无废城市建设和循环经济发展规划。In China,construction waste is increasing,and has a low recycling rate.Incineration slag is the largest secondary solid waste produced by municipal solid waste incineration.Exploring the feasibility of using construction waste and incineration slag to collaboratively produce self-compacting backfill material,focusing on the goal of multi-source inorganic solid waste resource utilization.Results showed that the addition of construction waste could increase the compressive strength of self-compacting backfill material by 10%~25%,while the addition of slag could reduce the compressive strength by 50%~75%.By leveraging the characteristics of both materials,it was feasible to achieve a combined addition ratio of 75%~85%for slag and construction waste in the production of self-compacting backfill material.This significantly enhanced the resource utilization rate of multi-source low-value inorganic solid waste,promoting the development of zero-waste cities and circular economy plans in our country.
