摘　　要：对废混凝土制成的再生粗细骨料和天然骨料的物理力学性能进行对比试验。结果表明:天然骨料的颗粒级配优于再生骨料;再生骨料比天然骨料密度低,吸水率、压碎指标、含泥量高;在采取一定措施后,废混凝土再生骨料基本可以代替天然砂石。In this paper,the basic physical and mechanical properties of waste concrete recycled aggregate were analyzed.By the contrast test of the waste concrete recycled aggregate and the natural aggregate,the aggregate,density,water absorption,crushing value,mud content were obtained.By comparing the results of physical mechanics tests of recycled aggregate and natural aggregate,it shows that the particle gradation of the natural aggregate is better than that of the recycled aggregate,while the other four properties of the natural aggregate is relatively poor than the recycled aggregate.
