Abstract

Canadian and American standards provide the compressive strength of concrete masonry assemblage as dependent on compressive strength of blocks, mortar type, and percentage of grout. It is common in construction to sporadically place non-standard units in masonry walls. Moreover, grout can have many different mix proportions causing a difference in compressive strength, stiffness, and grout-unit bond strength.

This research studied the effect of block geometry and the combination of two different block geometries on ungrouted prism strength. As well, this study focused on the effects of grout strength, grout stiffness, and grout-block bond strength on the compressive strength of grouted masonry prisms.

This study showed that block geometry affected prism compressive strength when the prism was comprised of one type of block. This was untrue for prisms with two different geometries. Grout strength and stiffness were found to affect prism strength. Bond strength was found to only affect the stiffness and not the strength of the grouted masonry prisms.
