CMU (Concrete Masonry Unit)

Category: infrastructure

A standardized rectangular block composed of portland cement, aggregate, and water, used as a primary structural building block.

CMUs serve as the structural backbone for commercial framing. Available in hollow or solid configurations, their internal cells are engineered to house vertical steel rebar and fluid grout mixes, delivering exceptional load-bearing, fire-containment, and acoustic insulation metrics.

Common Examples

• The commercial foundation design specifies structural eight-inch hollow CMU walls reinforced with vertical rebar cores.
• Using lightweight aggregate inside the CMU composition reduces the building’s dead load without sacrificing compression ratings.
