摘　　要：利用废弃混凝土加工成的再生骨料制作再生混凝土空心砌块。对再生混凝土空心砌块砌体进行抗压性能试验,研究不同再生粗骨料取代率对其受压性能的影响,分析了砌体的破坏特征和变形过程。研究结果表明:再生混凝土空心砌块砌体的受压性能和普通混凝土砌块砌体的受压性能极为相似,以85%再生粗骨料取代率,配制强度等级为MU5.0的再生骨料混凝土空心砌块是可行的。This paper engaged in the recycled aggregate concrete hollow blocks derived from waste concrete. An experimental study on the compression behavior of recycled aggregates concrete hollow block masonry was presented. The failure characteristic and failure process, ultimate bearing capacity were analyzed. The results show that the compression failure process of recycled concrete small hollow block walls was similar to the ordinary concrete hollow block walls： With the 85% replacement of the recycled coarse aggregate（RCA） by mass , it is feasible to obtained the recycled aggregate concrete hollow block whose design strength reached 5.0 MPa.

关 键 词：再生骨料混凝土空心砌块 再生粗骨料取代率 抗压强度
