What does CMU stand for in the context of masonry?

In the context of masonry, CMU stands for Concrete Masonry Unit. A Concrete Masonry Unit is a versatile and commonly used building block made from concrete and aggregates. It is designed for use in the construction of walls, foundations, and other structural elements. CMUs are known for their durability, strength, fire resistance, and thermal mass, making them an excellent choice for a wide variety of construction applications.

The properties of CMUs allow them to provide excellent structural support, while also offering good insulation when used correctly in wall assemblies. The manufacturing process involves mixing cement, water, and aggregates, which results in a standardized block that can be easily handled and laid in various configurations to meet design specifications.

Choosing this terminology over the others highlights its acceptance and common usage in the construction industry, as the other options do not reflect any widely recognized standards for masonry.
