CMU

Definition

A Concrete Masonry Unit (CMU) is a building block made of concrete, commonly known as a concrete block, used in construction.

Purpose

The purpose of CMUs is to provide strong, durable, and fire-resistant building materials for constructing walls, foundations, and other structures.

Examples of Use

• CMUs are used in the construction of load-bearing walls in commercial and residential buildings.
• They are commonly used for retaining walls and sound barriers due to their strength and mass.
• CMUs are used in modular construction, allowing for quick and efficient building assembly.

Related Terms

• Mortar: A mixture used to bond CMUs together.
• Reinforced Concrete: Concrete that is strengthened with steel rebar or mesh, often used with CMUs.
• Autoclave: A high-pressure steam chamber used to cure CMUs, enhancing their strength.

Notes

CMUs come in various sizes, shapes, and densities, making them versatile for different construction needs. They also offer excellent thermal mass properties.
