Experimental Investigation of Bond strength Autoclaved Aerated Concrete (AAC) Masonry

Abstract

Masonry walls can be load-supporting as well as non-supporting in which AAC blocks are utilized. Binding tenacity of autoclaved aerated concrete block-mortar interfaces formed of standard cement-sand mortars of various formulas and polymer-modified mortars is investigated in this study.It is presented a method for increasingnormal sand-cement mortar's binding strength without modifying the block surface qualities. Following the application of a thin cement-slurry coating to the block surfaces, a thick sand and cement mortar is poured. A triplet test was used to establish the brickwork's shear bond persistence, while a cross-couplet test was used to determine the tensile bond strength. Bond strength test’s failure patterns were investigated. The costs of AAC walls with various types of interfaces were then calculated.
