Compressive Strength of Double H Concrete Block Masonry Prisms

This study investigated the compressive strength of double H concrete block masonry prisms. A total of 42 (i.e., nine ungrouted, 15 half-grouted, and 18 full-grouted) specimens were tested under uniaxial compression. The effects of mortar strength, grouting, and grout strength on the compressive strength of the prism were discussed. The test results show that the compressive strength of H-block prisms decreased with an increase of grouting, although the ultimate load of the prisms increased greatly.
