摘　　要：混凝土骨料工程性能的优劣将直接影响到混凝土的质量。通过对再生混凝土骨料和天然骨料的基本物理性能试验对比分析,得到再生混凝土骨料较天然卵石骨料的吸水率高、表观密度及堆积密度小、压碎指标大;为配制符合工程性能要求的再生混凝提供参考依据,促进建筑废料的利用和"绿色建材"的应用。Advantages and disadvantages of the performance of concrete aggregate will directly affect the quality of concrete. Based on the basic physical performance test comparison analysis of the recycled concrete aggregate and natural aggregate, in comparison with the natural concrete aggregate, the recycled concrete aggregate has higher water absorption, smaller apparent density and bulk deusity, and larger crushed indicators. The paper can provide a reference to enable the recycled concrete made to meet the required working performance, which is favorable to the use of construction waste and the application of ＂ green building .
