摘　　要：再生混凝土骨料的基本特性直接影响到它的性能,因此研究再生骨料的性能显得尤为重要。着重比较了再生骨料和天然骨料在粒形、表观密度、堆积密度、吸水率、坚固性、压碎指标等方面的差别,分析了其产生不同的原因。The basic properties of recycled concrete aggregate directly affect its performance; therefore, the research on the properties of recycled aggregate is especially important. In this study, the grain shape, apparent density, bulk density, water absorption, sturdiness, crushing index were compared between the recycled aggregate and the natural aggregate. The causes of the differences were analyzed.

关 键 词：再生混凝土骨料 天然骨料 基本性能
