Concrete blocks are widely used in construction---in America, some houses are built using just concrete blocks, and no bricks. There are many benefits to concrete blocks, which is why they are such a popular construction material. It is strong yet lightweight, and can hold a number of surface finishes.
Concrete blocks, especially hollow blocks, are relatively lightweight when compared to bricks, and because of their size you only need to lay a few to cover a wide surface area. They are therefore easy to install, labour-friendly and, as a result, save on costs due to the time it takes to finish the construction.
There are a number of different types of concrete block, each with a specific density. This density brings with it a wide range of thermal properties, and so you can find the right block for your construction depending on the climate in which you are building. Dense blocks help to keep heat inside a building, while hollow blocks keep rooms cool.
Concrete blocks are a strong material, even more so if the blocks are reinforced with steel bars. Because of this it is a popular construction choice and holds an advantage over a more traditional brick construction. Because of the high strength of concrete blocks, you are able to construct a larger building with more stories than you could with a regular brick building.
Concrete blocks have a rough surface, and as such can hold a number of different surface finishes, such as render, stucco or paint. Each of these surfaces has its own aesthetic qualities, and so a surface to match all tastes can be found and easily laid onto a concrete surface.
Concrete is a non-combustible material, meaning that it has a great level of fire resistance. This gives it a distinct advantage over a timber frame house or building. It is also resistant to termites, so you won't have any problems with rotten or dry wood.
