摘要: 抗压性能是再生混凝土砌块砌体最主要的力学性能。通过抗压砌体构件的试验,研究再生混凝土砌块砌体的抗压强度、弹性模量、应力-应变规律及泊松比,并与GB 500032001《砌体结构设计规范》中普通混凝土砌块砌体计算公式相比较,给出了再生混凝土砌块砌体抗压强度设计值的建议取值。试验结果分析表明,再生混凝土砌块砌体具有很好的强度和变形能力,可作为承重墙体材料。

Abstract: Compression property is the main mechanical property of recycled concrete hollow block masonry.From the compression test of members for a masonry,it is researched the compression strength,elastic modulus,the stress-strain curve and Poisson ratio.At the same time the laws and test results are compared and analyzed in this paper,it is given the suggested design value of compression strength of this sort of masonry.The test results show that recycled concrete block masonry has better compression strength and ability of deformation,so it can be used for load-bearing wall material.
