Introduction of CMU Wall

What is CMU Wall?

Concrete Masonry Unit (CMU) Specifications

Concrete Masonry Units (CMU) Shapes

1. Single corner unit: - The single corner unit has only one end which is squared off. It is generally used at the end of the wall where the end of the block is exposed.
2. Stretcher Unit: - The stretcher unit has a flange extension on both of its ends. It is generally used in the middle of the walls where both ends are covered by the adjoining bricks.

Advantages of CMU Walls 

1. There are various advantages of CMU walls which are as follows
2. The concrete masonry unit walls are more durable as compared to the brick walls. The concrete masonry units are very easy to install and require very little maintenance. The CMU walls have good resistance to fire.
3. The construction of the CMU Walls is economical as compared to the brick walls.
4. The concrete masonry units are larger than conventional bricks.
5. The steel reinforcement is also used in the CMU walls which increases the load-bearing capacity of the CMU walls.
6. CMU walls are best suitable for areas with aggressive environmental conditions.

Disadvantages of CMU Walls

1. The concrete masonry unit does not have good resistance to water penetration.
2. The concrete masonry blocks require an additional coat to its surface to make it water-resistant which increases the cost.
3. Concrete masonry blocks have less thermal resistance.

Applications of Concrete Masonry Unit

1. The concrete blocks are used in the construction of the foundation walls and the basement walls.
2. The concrete masonry blocks are also used for the decorative purpose which will enhance the aesthetical view of the structure.
3. CMU is also used in the construction of the exterior walls as well as partition walls.
