横孔连锁混凝土空心砌块砌体抗压性能试验研究

摘要

为研究干砌法和湿砌法两种不同砌筑方法对不同型号横孔连锁混凝土空心砌块砌体抗压性能的影响，通过四组(24个)砌体试件的抗压试验，对其破坏特征、抗压强度进行对比分析。研究结果表明，干砌砌体在受压过程中先有裂缝产生、发展的过程，然后才丧失承载能力，而湿砌砌体多在未捕捉到裂缝的情况下直接被压溃，且后者的抗压强度明显高于前者；不同砌筑方法对较小尺寸砌块砌体抗压性能的影响更为显著。%In order to study the effect of dry masonry method and wet masonry method on compressive behaviors of different types of the cross bore chain concrete hollow block masonries, compression tests of four group (24) specimens were tested, and the differences between their failure characteristics and compressive strengths are analyzed. The results show that the dry masonry losses its bearing capacity after cracks appearing and developing, while the wet masonry is crushed without cracks appearing. The compressive strength of wet masonry is much higher than that of the dry masonry. The effect of different masonry methods on the masonry of smaller size is more obvious.
