When you are looking at concrete blocks, you will notice according to AAA Concreting, hat there are three different kinds out there such as interlocking, hollow, and there is also solid as well. A solid concrete block will be around fifty five percent solid and then a typical hollow block will be around twenty five percent solid. There will also be different categories and they will be classified by either the unit weight or by the density of the block.
A concrete block made for load bearing will have much more compressive strength compared to a concrete block used for landscaping or for pavement. There are also other methods used to improve the strength of the block, such as anchorage systems and reinforcing steel bars.
One of the most versatile materials out there is the cement block because they can be used for a lot of different applications and purposes.
There are concrete blocks for every kind of application such as decorative purposes, structural purposes, and even load bearing purposes as well. A load bearing block can be a veneer which is used to support retaining walls or a roof. However, these applications may require that the blocks are reinforced with steel bars due to the amount of weight they are supporting. Concrete blocks can come in a number of different shapes but they are usually in a square or in a rectangle. The thickness of the block can be as small as 40mm to as big as 100mm. And it is possible to customize the concrete blocks to meet your requirements and purpose as well, so do not forget that is always an option.
How to Install
When you are installing a concrete block, you will usually need to use some mortar. Before you install, it is important to have a good foundation set up as well and this will be dictated by the kind of thing you are installing. You will need to smooth out the mortar each time you place a block as well, so that is something to take into thought.
Another method to install concrete blocks is called the dry stack method. Hollow blocks can be used for this as well. The blocks are laid course by course without a mortar. When the course is being laid out, the finished course will need to be filled up with gravel or crushed stone. This is vital because the back fill will ensure that the building will remain much more stable. Interlocking blocks will not need to have mortar in order to be installed as well, so that is another thing to think about. A common interlocking cement block will either have a lug or a lip on the bottom. So when the course is being laid out, the blocks will lock up with one another which will make the structure very strong and also durable.
The method used will be dictated by the purpose and the structure because not every building can be constructed using the same exactly kind of method. Generally, a building will want to be made out of using the mortar method. And landscaping application can use the interlocking method.
