“…However, very little is known about their performance in mortars used for masonry. In what appears to be the first such study, Polyvinyl Acetate (PVA) fibres were investigated for flexural bond with clay bricks by Armwood et al [18]. They found that although the post-peak response in mortars improves with an increase in the fibre content, the strain at failure in a masonry unit was smaller so that the flexural bond failed sooner and the benefits from the 0950-0618/$ -see front matter Ó 2011 Elsevier Ltd.

“…However, very little is known about their performance in mortars used for masonry. Armwood et al [11] concluded that the total fibre content should be restricted to an upper limit of 0.6% volume fraction. Recently Chan and Bindiganavile [12] studied the effect of polypropylene micro-fibres on the flexural behaviour of hydraulic lime mortar up to 0.5% volume fraction.…”

This paper evaluates the fracture parameters of bond in stone masonry units bound with plain and fibre reinforced mortar. Sandstone blocks were joined together with a modern Type S mortar conforming to CSA A 179-04. A companion series was examined employing a hydraulic lime mortar used in the repointing of historical masonry. Based on a previous study, polypropylene micro fibres were incorporated at up to 0.5% by volume to achieve superior crack growth resistance. The study reports relevant fracture parameters including the critical stress intensity factor, the critical crack length and the critical crack mouth opening displacements. The masonry units were subjected to quasi static flexure as per ASTM and dynamic bending via a drop weight impact machine which generated stress rates up to 10 7 kPa/s. The results show an improvement in the bond strength, but varied fracture performance between the Type S and hydraulic lime mortars, as a result of fibre reinforcement.
