摘　　要：对再生混凝土小型空心砌块砌体进行抗压性能试验,研究不同砂浆强度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:再生混凝土小型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基本相似,极限状态均为砌体被贯通的裂缝分隔成小立柱后被压坏。通过对试验数据的分析得出,再生混凝土小型空心砌块的受压强度可采用《砌体结构设计规范》(GB50003—2001)建议的公式进行计算。An experimental study on the compression behavior of recycled aggregates concrete small hollow block masonry was presented.The failure characteristic and failure process,ultimate bearing capacity were analyzed.The results of the test show that the compression failure process of recycled concrete small hollow block walls was similar to the ordinary concrete hollow block walls,which was destroyed after the main crack forms and penetrates the specimen.The compression strength of specimen was calculated according to Code for design of masonry structures（GB50003—2001）.The calculating results are less than the experimental results,so that the compression strength of recycled concrete hollow block can be calculated using the formula in Code for design of masonry sturctures（GB50003—2001）.
