摘　　要：对废混凝土再生粗骨料的压碎指标、表观密度、吸水率进行分析,并对以此为粗骨料的再生混凝土与普通混凝土按照相同设计配合比进行了试验,对强度、弹性模量等指标进行了量化分析与对比,得出两者基本性能方面的差异,以探索试验以循环经济为基础对废弃混凝土再次利用。The waste recycled coarse aggregate concrete crushing value,apparent density,water absorption and tested the same mixture ratio design two kind of concrete：Take waste concrete as thick aggregate regeneration concrete and ordinary concrete.Quantitative analysis and comparison of indicators such as intensity,elasticity coefficient and so on,obtains the differences between the two basic performance.Then Probe test of circular economy based on waste concrete reuse.

关 键 词：废弃混凝土 再生骨料 基本性能
