Experimental evaluation of masonry building walls behavior made of AAC block and shear strength of it mortar

Due to many advantage of Autoclaved Aerated Concrete (AAC) such as lightweight, low thermal conductivity and fire resistance its usage is increasing day by day. In this paper first the compressive and shear strength of mortar and blocks was given then the result of three wall specimens with dimensions 120 × 120 ×25 cm under diagonal loading was studied. In spite of suitable shear resistant of mortar, sliding did not occur at mortar/blocks interface. In all wall specimens, failure occurred on the blocks because block's shear resistance is less than mortar.
