CMUs could also be formulated with special aggregates to provide particular colours or textures for finish use. Special textures could also be produced by splitting a ribbed or stable two-block unit; such factory-produced models are known as “split-rib” or “split-face” blocks. Blocks could also be scored by grooves the width of a mortar joint to simulate totally different block modules. For example, an 8-by-16-inch (200 mm × 410 mm) block may be scored in the center to simulate 8-by-8-inch (200 mm × 200 mm) masonry, with the grooves full of mortar and struck to match the true joints.
