摘　　要：研究分析了水灰比对废砖再生粗骨料混凝土各种强度指标的影响。在试验数据的基础上,通过统计回归,初步给出了废砖再生粗骨料混凝土立方体抗压强度与其他强度指标之间的换算关系。试验结果表明:废砖再生粗骨料混凝土各种强度均比普通混凝土要低,其强度换算关系并不同于普通混凝土。The influence of different water cement ratio on the strength of waste brick recycled coarse aggregate concrete was investigated. Based on the experimental data, the relationships between the cubic compressive strength and other strength are obtained. It is showed that the every strength of waste brick recycled coarse aggregate concrete is lower than ordinary concrete and the inter-relationships of strength indexes of waste brick recycled coarse aggregate concrete is different from that ordinary concrete.
