Fluted concrete unit masonry has ribbed or fluted edges. Units typically have four, six, or eight ribs vertically aligned to form continuous segments in the finished wall. The fluted units can be smooth, split, or striated. Flutes can be produced to provide either a circular or rectangular profile. Fluted concrete masonry units can be specially fabricated to be water repellent, and are produced in an array of colors.

Fluted concrete masonry units are usually laid so that the flutes or ribs align vertically as they are placed. Masons can utilize different bond patterns, such as stack bond or one-third running bond, to align scores in adjacent courses. The bond pattern used will determine the load bearing capacity of the wall.

Exposed aggregate concrete unit masonry, also described as "burnished" or "honed", uses ground face concrete masonry units that are polished after manufacturing to achieve a smooth finish which reveals the natural aggregate colors. The units have the appearance of polished natural stone. The finished look of the ground surface can be altered by changing aggregate type and proportions. Often, specific aggregates will be used to enhance the appearance of the polished surface, while coatings are sometimes used to deepen the color. Ground face units are often scored to achieve a scale other than the conventional 8 x 16 in.

Sandblasted face units are CMU where sand (or abrasive) blasting is used to expose the aggregate in a concrete masonry unit, resulting in a "weathered" look.
