蒸压加气混凝土砌体抗压强度试验研究

Experimental study on the compressive strength of autoclaved aerated concrete block masonry

主要研究了蒸压加气混凝土砌体的轴心抗压强度,讨论蒸压加气混凝土砌体的裂缝发展特点和破坏特征及其影响因素,分析其抗压承载力、弹性模量及应力应变关系,并与传统砌体材料进行对比分析。结果表明蒸压加气混凝土砌体开裂后砌体还可以承受一定的压力,延性较好;蒸压加气混凝土承重砌块砌体的强度与传统承重砌体的强度水平相当,完全可以用于多层住宅房屋的承重结构。

The paper describes the axis compression tests on autoclaved aerated concrete block, discusses the characters of crack, destroy features and the influence factors on destroy for the masonry. And analyzes its compressive capacity, elastic modulus and stress-strain relationship, compares with the traditional masonry materials. The results show that autoclaved aerated concrete block masonry can bear certain pressure and also has a better ductility when block appears cracks. The strength of load-bearing autoclaved aerated concrete block masonry is equivalent with traditional load-bearing block masonry, which can be used in load-bearing structure of multi-storey residential house.
