摘要
通过对再生混凝土砌块砌体的抗压强度和抗剪强度试验,探讨了砌体的破坏过程和破坏形态,并根据试验结果分析了再生混凝土砌块砌体强度与砌块强度和砂浆强度的关系。基于试验数据计算了再生混凝土砌块砌体的强度标准值和设计值。研究结果表明:再生混凝土砌块砌体与普通混凝土砌块砌体的力学性能基本一致,且具有较好的抗压稳定性;普通混凝土砌块砌体的抗压强度和抗剪强度计算公式适用于再生混凝土砌块砌体。
The experiment of compressive strength and shear strength of the recycled concrete hollow block masonry was conducted to investigate the failure process and failure mode of the masonry .Based on the experiment results , the relations between the strength of recycled concrete hollow block masonry and the strength of block and mortar were analyzed .The standard value and design value of strength for recycled concrete hollow block masonry were calculated based on the experiment data . The results show that the mechanical properties of recycled concrete hollow block masonry are basically in accordance with those of the normal one ,and the quality stability is satisfactory . The calculation formulae of compressive strength and shear strength of normal concrete hollow block masonry can be applied to the recycled concrete hollow block masonry .
