![]() The concrete masonry blocks require an additional coat to its surface to make it water-resistant which increases the cost.The concrete masonry unit does not have good resistance to water penetration.There are also some disadvantages of CMU wall construction which are as follows CMU walls are best suitable for areas with aggressive environmental conditions.The steel reinforcement is also used in the CMU walls which increases the load-bearing capacity of the CMU walls.The concrete masonry units are larger than conventional bricks.The construction of the CMU Walls is economical as compared to the brick walls.The CMU walls have good resistance to fire. The concrete masonry units are very easy to install and require very little maintenance. The concrete masonry unit walls are more durable as compared to the brick walls.There are various advantages of CMU walls which are as follows.The compressive strength of the concrete masonry unit mainly depends upon the mix design and the quality of concrete used in the manufacturing of the concrete masonry blocks. The concrete masonry walls have compressive strength which ranges from 7MPa up to 35 MPA. The compressive strength is one of the most important criteria which should be tested before using any construction material or building unit. Normal weight CMU blocks: The weight of the normal weight CMU blocks is more than 125 fb/ft 3.Medium weight CMU blocks: The weight of the medium weight concrete masonry blocks ranges between 105 fb/ft 3 to 125 fb/ft 3.Lightweight CMU Blocks: The weight of the lightweight cinder blocks is less than 105 fb/ft 3.The concrete block units are classified into three categories according to their weight The weight of the cinder blocks or Concrete masonry units mainly depends upon the density of the concrete used in the manufacturing of the concrete blocks.

Bullnose blocks: – The bullnose blocks are also available in the market with one end rounded. ![]() Cap Units: – The Cap units are the solid and thin concrete blocks that are generally used to open the cavities at the top of the concrete block walls.These are used around the windows and door openings to provide the expansion space. Sash units: – Sash units have slots cut in the flat ends.This type of block is generally used to create vertical pillars. Double corner unit: – The Double corner unit has two ends that are squared off.It is generally used in the middle of the walls where both ends are covered by the adjoining bricks. Stretcher Unit: – The stretcher unit has a flange extension on both of its ends.It is generally used at the end of the wall where the end of the block is exposed. Single corner unit: – The single corner unit has only one end which is squared off.The CMU concrete units are available in various shapes in the market which are as follows. In this article, we will discuss all about the concrete masonry units. The CMU blocks are available in various shapes and sizes in the market and are widely used in the construction of walls of the building.
