刻槽对粉煤灰实心砖砌体结构抗剪强度影响研究

Effect of Grooving on Shear Strength of Solid Brick Masonry Structure with Fly Ash

蒸压粉煤灰砖砌体易开裂和耐久性较差,多用于多层砖混结构墙体。试验在标准蒸压粉煤灰砖表面设计四种不同面积的砂浆槽,砌成试验用双剪试件,通过抗剪强度试验测得极限剪切破坏强度,并与无刻槽的砖砌体试件进行对比,验证砂浆槽对砌体强度的影响,探讨提高蒸压粉煤灰砖砌体抗剪强度的可能性。

Autoclaved fly ash brick masonry wall cracking and poor durability, mostly used for multi-layer brick masonry structure wall.In this paper, four kinds of mortar groove were designed on the surface of standard autoclaved fly ash brick to test the ultimate shear failure strength through shear strength test, and compared with brick masonry specimens, to verify the effect of mortar groove on masonry strength.
