##### Compressive Strength of Brick Masonry - The Constructor

Dec 05, 2012  The compressive strength of a wall depends on the strength of the units used, the bricks or blocks, and the mortar. The assessment of the combined strength of the elements will also be affected by the degree of quality control exercised in manufacture and construction. The slenderness ratio, in turn, depends upon the effective height (or length ...
