Concrete Masonry Construction
The concrete masonry units are laid with cement mortar, which binds them together to create a composite structure. There are many types of masonry walls but the most common is the concrete masonry unit (CMU). They are frequently used in the construction of commercial, residential buildings, and factories.
Advantages of Concrete Masonry
It is durable, strong and won’t dent from hail/ stones or from accidental car bumpings in the parking lot. It requires low maintenance as its color doesn’t fade or rust.
Concrete masonry units are available in a variety of colors, textures, shapes, and sizes. Architectural concrete masonry units blend in with the natural beauty of urban and rural areas.
Masonry concrete not only has fire resistance properties but also stands up to high wind forces and earthquakes. It can withstand a large amount of compressive force. Thus, it protects your investment in your building and lower insurance rates. It also gives you better resale value.
The masonry concrete wall buildings are more economical, with lower overall heating and cooling costs due to having high thermal mass. Masonry also offers sound attenuation which provides quiet and comfortable atmosphere for the inhabitants. It also offers high resistance against rotting and pests.
Concrete masonry units are manufactured and are ready for delivery in a shorter period of time making it convenient than other options.
Types Of Concrete Masonry
Concrete masonry units are categorized based on the weight where heavyweight and normal weight are used as structural masonry units and lightweight units are used as veneers or for non-load-bearing conditions.
The concrete block comes in many sizes and shapes. The most common are:
1. stretcher unit
2. single corner unit
3. double corner unit
4. sash units
5. cap units
6. bullnose blocks
7. partition blocks
8. lintel blocks
9. architectural masonry units
Concrete Masonry Construction
A brief overview of concrete masonry construction is described below:
1. Create a foundation layout
The first step is to layout the simple rectangular outline of the foundation.
Excavate earth for the foundation to create a flat-bottom trench to pour a block of concrete for supporting the cement block wall.
3. Pour the Foundation
Concrete is poured into a hollow form lining the sides of the excavation trench and leveled. Construction of the wall is started only after it has completely hardened and cured.
4. Lay the First Course of Block
An outline for the cement block wall is marked onto the surface of the foundation, using a chalk line. The thick layer of approximately 1-inch layer mortar is laid onto the foundation inside this outline. The first course of cement blocks are positioned into the mortar and tapped so that they are embedded in the foundation mortar. Subsequent blocks are then joined with previous blocks after the end of blocks are covered with mortar. Mortar helps prevent moisture and air leakage and provides reinforcement to the structural unit.
5. Cut Blocks
This is done with a power saw fitted with a masonry blade, along with a masonry chisel and hammer.
6. Lay Subsequent Courses of Block
The second and subsequent blocks are installed in the same fashion as the first.
7. Add Reinforcement
The horizontal joint should be reinforced with metal reinforcement strips laid into the mortar after every third or fourth course of blocks. This increases strength and ductility and prevents shrinkage cracking.
8. Finish the Joints
Finishing tools are used to lightly press into the mortar.
9. Lay Cap Blocks
The tops of cement block walls are covered with solid concrete cap blocks.
Masonry surfaces should be cleaned to remove stains, debris and mortar, and grout droppings.
