摘 要:为了使承重型横孔连锁混凝土小型空心砌块用于村镇的砌体结构,需要测定该砌块的物理力学性能。本文根据相关规范的试验方法对该砌块进行了基本的物理力学性能试验。试验结果表明,密度、空心率、吸水率、相对含水率、干缩值、软化系数、抗冻性等均满足现行规范要求。承重型横孔连锁混凝土小型空心砌块的强度等级达MU10级,可以用于砌体结构的承重墙。Abstract: In order to use load bearing horizontal-hole interlock concrete small hollow block in rural masonry structures, physical and mechanical properties of block are determined. According to relevant specification, basic physical and mechanical performance experiment of block is carried out in this paper. The experimental results show that, the proposed block can satisfy current specification of density, the hollow rate, water absorption, the relative water content, dry shrinkage, softening coefficient and frost resistance, and its strength reaches MU10 which may be used for masonry-structured load bearing walls.
