Masonry as history knows it, makes use of blocks of cut stones such as granite, marble and travertine. Also in use centuries ago are man-made blocks made of clay. While these are ideal in most applications, they are not the most economical or the easiest to work with. In fact, these blocks can be pretty expensive.
As an economical alternative, a cast concrete also known by other names such as concrete blocks, foundation blocks, and cement blocks can be acquired at a much lower price. It is now the standard material used in a wide variety of masonry applications. As such, concrete masonry can be simply described as masonry work that makes use of cast concrete blocks instead of the traditional cut stone blocks.
Different Types Concrete Blocks
To meet the demands of different industrial applications, the regular concrete block comes in many different sizes. In the United States, perhaps the most commonly used is the one that measures 16×8×8 inches. But this is only the advertised measurement. It is in fact smaller by 3/8 inches. This is an allowance to allow mortar joints.
Also, concrete blocks can be made of different components. Each one also possesses a different level of strength and durability. For example, high density blocks are made from a mixture of crushed gravel and sand. As for the low density variants, these are typically made of industrial wastes. One example is the cinder block made of ashes.
Different Applications
Concrete masonry has a wide range of industrial applications. For tall buildings, walls made of concrete blocks are preferred because these can possess considerable strength of structure without being too thick. The concrete block is advantageous in this aspect when compared traditional masonry which uses blocks of stones or bricks.
Also, concrete blocks are ideal for use on top floors. In which case, lightweight concrete blocks may be used. This is advantageous because traditional blocks made of cut stones can be pretty heavy. If these are used, they can strain the lower floor levels with too much mass. The structure will be unstable and potentially dangerous.
Concrete masonry is also ideal for regular residential homes. It provides an economical solution that is not as expensive as traditional masonry. Moreover, the hollow structure of a concrete block is ideal for structures inhabited by people. This is because a hollow block possesses good insulation properties.
Strength Of Structure
Alright, so it is the more economical choice in masonry right? But how about the strength, is it still up to the task? As you know, it is quite common that cheaper alternatives are also less durable and less durable. Is this also true for concrete masonry?
Well, it is not necessarily the case. Concrete masonry is widely used worldwide and the strength it provides on structures is commendable. In fact, depending on the type of concrete block used, a wall or floor made with concrete blocks can withstand 1,000 up to 5,000 psi.
Therefore, concrete masonry can safely be called the modern version of the traditional one. It is still up to the task when it comes to strength and it is economical as well.
