Which construction material is classified as masonry?

Masonry refers to a construction technique that involves the use of individual units bonded together with mortar. These units are typically made from materials such as bricks, stones, concrete blocks, or other forms of solid materials that create a strong and durable structure. Concrete blocks, also known as concrete masonry units (CMUs), fit this definition perfectly as they are solid rectangular blocks made from concrete, which is a key characteristic of masonry.

Understanding the properties of masonry materials is crucial in firefighting and building construction since masonry structures often offer better fire resistance compared to wood and some other materials. This is essential knowledge for firefighters when assessing structural integrity during emergencies.

In contrast, wood, steel, and plastic composites do not fall under the category of masonry materials. Wood is an organic material with different fire behavior characteristics. Steel, while a strong construction material, is not classified as masonry because it does not consist of units bonded by mortar. Plastic composites, although they are used in various construction applications, lack the properties and characteristics associated with traditional masonry materials.
