（郑州大学土木工程学院，郑州 450002）[摘要] 通过对再生混凝土空心砌块砌体的抗压、抗剪等基本力学性能进行试验，研究了再生混凝土空心砌块砌体在不同砂浆强度下的抗压性能以及抗剪性能。研究表明：再生混凝土空心砌块砌体的抗压性能和抗剪性能与普通混凝土空心砌块的基本相似，抗压强度可采用《砌体结构设计规范》（GB 50003—2011）建议的公式计算，砌体的通缝抗剪强度小于普通混凝土空心砌块砌体的抗剪强度，通过对试验数据的回归分析，提出了再生混凝土空心砌块砌体的抗剪强度平均值以及设计值的计算公式。[关键字] 再生混凝土空心砌块;抗压强度;抗剪强度中图分类号：TU522.3+9 文献标识码：A 文章编号：1002-848X(2013)S2-0576-05作者简介：郝彤，博士，教授，主要从事混凝土和砌体结构基本理论及工程应用研究，Email:haotong@zzu.edu.cn。Experimental study on the basic mechanical properties of recycled concrete hollow block masonryHao Tong , Dong Li(College of Civil Engineering, Zhengzhou University, Zhengzhou 450002, China)Abstract: By the experimental study on the basic mechanical properties of recycled concrete hollow block masonry, the compressive and shear behavior of recycled aggregate concrete hollow block masonry under different mortar strength were analyzed .Research indicats that the compressive and shear behavior of recycled aggregate concrete hollow block masonry are similar to that of ordinary concrete hollow block masonry. The normal formula is recommended to calculate the compressive strength of the masonry. The shear strength calculation formula of recycled concrete hollow block masonry is proposed according to the formula of masonry design code. The calculating results are in good agreement with the test results.Keywords: recycled concrete hollow block masonry; compressive strength; shear strength
