What type of masonry is typically associated with the use of CMUs?

Concrete masonry is associated with the use of Concrete Masonry Units (CMUs), which are also commonly referred to as cinder blocks or concrete blocks. CMUs are manufactured from a mixture of cement, water, and aggregates, resulting in a durable, versatile material that is widely used in a variety of construction applications.

This type of masonry is prevalent for structural wall construction, foundations, and even aesthetic facades, because of its strength, fire resistance, and insulating properties. The modular dimensions of CMUs facilitate easier handling and construction, allowing for efficient assembly and the ability to easily integrate reinforcement within the walls, enhancing their load-bearing capacities.

In contrast, brick masonry typically utilizes clay or sand to form bricks, while stone masonry employs natural stones, both of which do not involve the specific use of CMUs. Wood paneling, on the other hand, is not masonry at all, as it involves wood materials rather than stone, concrete, or masonry units. As a result, concrete masonry stands out as the correct association with CMUs in this question.
