摘　　要：系统研究在水灰比相同的情况下,再生粗骨料取代率不同混凝土的力学性能。试验结果表明,随着再生骨料掺入量的增加,混凝土的坍落度、回弹值、抗压强度、劈裂抗拉强度都有不同程度的降低。This article system research concrete mechanics performance in same water-cement ratio situation and different recycled coarse aggregate replacement percentage.The test result indicated that along with mixes increasing again in the recycled aggregate,the concrete slump、rebounding value、compressing strength and tensile splitting strength were reduced in different degree.

关 键 词：再生粗骨料 再生混凝土 取代率 力学性能
