摘　　要：简单介绍了建筑垃圾处理源头处理减量及资源化方向,及国内一些利用建筑垃圾的工程案例。介绍了目前城建集团河北环科分公司加工的建筑垃圾再生骨料的性能,再生细骨料与目前北京市大量的天然砂的性能对比,满足要求的再生粗骨料中红砖含量的限定。还介绍了使用再生骨料生产的实心混凝土普通砖、混凝土路面砖、混凝土砌块的物理性能参数,证明了再生骨料在生骨料生产的实心混凝土普通砖、混凝土路面砖、混凝土砌块应用的可行性。The paper briefly introduces the reduction and resource utilization of construction waste treatment sources,as well as some engineering cases of using construction waste in China.The article introduces the performance of the construction waste recycled aggregate processed by the Hebei Branch of the Urban Construction Group.The perfor?mance of the recycled fine aggregate and the current large amount of natural sand in Beijing meets the requirements of the red brick content of the recycled coarse aggregate.And also introduces the physical performance parameters of sol?id concrete bricks,concrete pavers and concrete blocks produced by recycled aggregates,and proves the application feasibility of solid aggregates,concrete pavers,concrete blocks of recycled aggregates are produced in raw aggregates.
