摘　　要：介绍了再生混凝土的研究背景及目的,并针对碎砖类骨料再生混凝土的配合比设计进行了试验研究。试验结果表明:经优化设计合理的配合比,利用拆除既有建筑物的碎砖替代部分天然碎石骨料制备混凝土是可行的。The background and purpose of the recycled concrete were described.Experimental study was carried out on the subject ＂The ap- proach for the proportion design of recycled brick aggregate concrete＂ .The experimental results showed that reasonable proportion design of opti- mization, using the brick from the demolition of existing buildings to replace part of natural aggregate was feasible for concrete preparation.

关 键 词：再生混凝土 碎砖骨料 配合比设计
