Brick-Mortar Bond and Masonry Compressive Strength

Publication: Journal of Materials in Civil Engineering
Volume 17, Issue 2

Abstract

This paper focuses on some issues pertaining to brick-mortar bond and masonry compressive strength. Failure theories for masonry under compression make the assumption that the bond between brick and mortar remains intact at the time of failure of the brick or mortar. The influence of bond strength on masonry compressive strength is not fully accounted for in these failure theories. In this investigation, the influence of bond strength on masonry compressive strength has been examined through an experimental program using local bricks and mortars. Masonry prism compressive strength has been determined when the brick-mortar bond strength is varied over a wide range without altering the strength and deformation characteristics of the brick and mortar. Brick-mortar bond strength has been determined through flexure bond strength and shear bond strength tests. A relationship between the masonry prism compressive strength and bond strength has been obtained. The results clearly indicate that an increase in bond strength, while keeping the mortar strength constant, leads to an increase in the compressive strength of masonry.
