Compressive strength and deformation characteristics

This research presents a detailed study on the compression behaviour of concrete hollow and solid block masonry manufactured from different types of mortars, beddings and block types. The employed mortar grades are designated as M2, M3, and M4 as in Australian Masonry Standards (AS3700 ) based on their mix ratios. According to this standard, all three types of mortars can be used with clay bricks while concrete block masonry can be designed using M3 mortar

COMPRESSIVE STRENGTH TESTING VARIABLES FOR

When coupons are used as compression specimens, they are cut at an h/t of 2, so correction factors are not needed. Figure 2 illustrates the effect of aspect ratio on apparent compressive strength of solid specimens. Hollow concrete masonry units are less affected by variations in h/t. For example, research has shown little change in apparent ...
