蒸压灰渣页岩砖砌体抗压及抗剪性能试验研究

通过对3种砂浆砌筑的24件蒸压灰渣页岩砖砌体试件的轴心抗压试验与通缝抗剪试验,分别对该砌体在轴心压力与剪力作用下的抗压性能与抗剪性能进行试验研究,分析了该砌体的破坏特征、抗压能力与抗剪性能。研究表明：轴压试验中,与黏土砖相比蒸压灰渣页岩砖砌体的初始裂缝出现较早,砌体的抗压强度随着砂浆强度的提高而提高。砌体通缝抗剪试验试...

Experimental investigation of compressive and shear properties of autoclaved ash ahale brick masonry

Compressive properties and shear properties of autoclaved ash shale brick masonry were studied through experiments on 24 brick masonry specimens which were made from three kinds of mortar under axial pressure and shear.Failure characters、compressive properties and shear properties of the brick masonries were investigated.The result shows:the cracks emerged earlier compaing with the clay brick in the compressive tests.The compressive strength increases with the mortar strength increasing.The failure characters of autoclaved ash shale brick masonry shear tests were brittle similar to the clay bricks.
