自保温混凝土砌块砌体抗压及抗剪性能试验研究

Experimental research on compressive and shear performance of composite thermal insulation concrete block masonry

自保温混凝土空心砌块是一种新型的节能砌块,主要应用于框架结构的填充墙。为研究非承重自保温混凝土空心砌块砌体的基本力学性能,探讨了3种不同砌筑砂浆强度下自保温混凝土空心砌块砌体的抗压强度和抗剪强度。结果表明,自保温混凝土砌块砌体的受压过程类似于一般混凝土空心砌块,只是裂缝出现的部位不同;自保温混凝土砌块砌体的抗剪强度主要取决于砌筑砂浆强度,并随着砌筑砂浆强度的增大而增大。

The composite thermal insulation concrete block masonry,as a type of new thermal insulation masonry,is mainly applicable for infill wall of frame structure. In order to study its basic physical performances, the compressive strength and shear strength of this masonry under three different mortar strengths were carried out. The results show that the process of compression is similar with the normal concrete block masonry,only the position of the crack is different. The shear strength is depended on the mortar strength,and the shear strength is increased with the increasing of the mortar strength.
