Strength, behavior, and failure mode of hollow concrete masonry constructed with mortars of different strengths

This study reports the failure modes of hollow concrete masonry prisms, taking into account the block and mortar stress-strain behavior. An extensive and detailed experimental program has been conducted on three-block high stack-bonded prisms, built using a combination of one hollow block type and three mortars with different strengths. Based on the results of the experiments, masonry failure was assessed. The main conclusion of this is that the...
