Investigation of Masonry Bond and Surface Profile of Brick

Source

The original objective of this research was to investigate the influence of masonry cements on flexural bond of mortar to clay brick units and on the water penetration of masonry assemblies fabricated using these materials. The test variables included 20 masonry cements and 11 types of brick, each representing materials produced in different areas of North America. Results of flexural bond strength tests on masonry assemblies indicated that factors other than mortar composition affected bond strength. Accordingly, an investigation was made to evaluate the effect of surface texture of clay brick units on bond strength. A surface profilometer, from which results could be quantified, was used for this work. Results suggest that surface texture of the brick is a primary factor in the development of bond strengths.
