Description: Mortar-to-masonry bond is a critical component that affects not only the strength of the masonry construction but also its durability. While traditional mortar uses fine sand only, this investigation examines whether the addition of small steel fibres to the mortar mix increases the masonry bond strength. Bond wrench tests carried out in accordance with AS3700-2011 were used to determine the tensile strengths. Image analysis techniques and microscopic examinations were used to examine the failure surfaces as well as the mortar-brick interface to better understand the bond phenomenon. To gain a greater understanding of the effects that the fibres may have on the flexural bond strength, the proportion of fibres and the presence of lime were considered. It was found that some benefits could be obtained from the addition of the fibres where failure involved surface debonding.
