摘　　要：由于再生骨料吸水率大,表面粗糙且棱角多,导致在配合比相同的情况下,再生混凝土存在坍落度小、经时损失大的问题。在试验的基础上,采用3种配合比改进方法解决上述问题,并就3种配合比对再生混凝土物理力学性能的影响进行了分析。High water absorption, rough surface and more angularity of recycled aggregate cause small slump constant and great loss by time of reclaimed concrete under the same mixing proportion, On the basis of experiments, three mixing proportion methods are adopted to solve above problems and the influence of three mixing proportion on physical and mechanical properties of reclaimed concrete are also analyzed.

关 键 词：再生骨料 再生混凝土 配合比 力学性能
