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。在混凝土空心砌块配合比参数优化设计的基础上,以再生骨料混凝土空心砌块抗压强度作为评定指标,采用正交试验方法,研究再生骨料混凝土空心砌块配合比设计。研究结果表明:对于再生骨料混凝土空心砌块,以85%再生粗骨料取代率和100%再生细骨料取代率,选取合适配合比,其强度等级是可以达到MU5.0的。This paper engaged in the recycled aggregate concrete hollow blocks derived from waste concrete. On the basis of the parameter optimization design of proportion of concrete hollow block, recycled aggregate concrete hollow block compressive strength is considered as evaluation indexes. The mixed proportion design of recycled aggregate concrete hollow block were analyzed by the orthogonal experimental design. The results show that if the selection of mixed proportion is proper, The compressive strength of recycled aggregate concrete hollow block can reach to MU5.0, with 85% replacement of the recycled coarse aggregate（RCA） by mass and 100% replacement of the recycled fine aggregate （RFA） by mass.
