摘　　要：为了增强建筑垃圾再生粗骨料在混凝土中的应用,采用了有机预处理的方法对再生粗骨料进行了改性增强,选用沥青、白乳胶及脲醛树脂三种有机浆液分别对再生粗骨料进行浸润预处理试验,对预处理后的粗骨料进行基本性能测试,结果表明脲醛树脂预处理后的再生粗骨料性价比最优,为再生粗骨料的强化提供一条新的途径。In order to modify and strengthen the coarse aggregate recycled from the rural construction waste using the organic pretreatment method so that the processed recycled coarse aggregate can be applied to concrete,this essay chose three kinds of organic serum,white latex adhesive,asphalt and lauxite,to get the recycled coarse aggregate soaked in respectively in the pretreatment experiment,then tested the basic property of the recycled coarse aggregate after pretreatment.The results showed that the recycled coarse aggregate with the most optimal cost performance were those pretreated by lauxite,which could provide a new way to strengthen the recycled coarse aggregate.
