中文摘要：

制作了再生骨料掺入量为75%的再生混凝土多孔砖,进行了再生混凝土多孔砖砌体块材抗压及抗折试验。试验结果表明,再生混凝土多孔砖块材抗压强度平均值为8.46 MPa;同时,进行了再生混凝土多孔砖砌体抗剪性能试验,考察了再生混凝土多孔砖砌体在不同砂浆强度下的抗剪承载力,分析了再生混凝土多孔砖砌体受剪破坏特征。在此基础上,通过对试验数据的回归分析,提出了再生混凝土多孔砖砌体抗剪强度计算公式。

英文摘要：

Recycled aggregates concrete perforated bricks are produced using 75% recycled aggregates dosage.The compressive strength and flexural strength tests of recycled aggregates concrete perforated brick masonry are carried out.The experimental results show that the average compressive strength of recycled aggregates concrete perforated brick masonry is 8.46MPa,and the shear behavior tests for recycled aggregates concrete perforated brick masonry are carried out.The shear bearing capacity of recycled aggregates concrete perforated brick masonry under different mortar strengths is investigated,and the characteristics of shearing-failure of recycled aggregates concrete perforated brick masonry are analyzed.Based on the test results,the shear strength calculation formula of recycled aggregates concrete perforated brick masonry is proposed according to the regression analysis of experimental data.
