Grout and Reinforcing Section 2.3 masonrybc

Coarse Grout, the most commonly used type of grout, has a maximum aggregate size of 12 mm (1/2"). The slump should be between 200 and 250mm (8"-10"). This is much higher than typical ready-mix concrete, but is very necessary to properly fill the cores of masonry units and flow around reinforcement or other elements within the wall.
