Concrete Block (CMU) - Construction Material Guide & Uses #31367 (License: Personal Use)

This illustration shows a typical 8-inch concrete masonry unit (CMU) with three hollow cores, designed to reduce weight while maintaining structural integrity. The block features flanged ends for interlocking and a textured surface for improved mortar adhesion. CMUs are widely used in commercial, industrial, and residential construction due to their fire resistance, thermal mass, and acoustic performance.
