What is a specific block?

As the name suggests, the concrete block is a building or building block made of concrete. Concrete is the merger of Portland cement, aggregate and water. The unit used in the production of a concrete block is often an ash or lower ash. The rest or ashes of the bottom ash, or cinders resulting from burning coal. Therefore, some concrete blocks are known as cinder blocks. These blocks weigh about 40 to 45 pounds (18.14 kg to 20.41 kg). The blocks may be solid or contain large holes in the middle. Cement blocks, known as concrete bricks, made according to the specifications of conventional red bricks, are also available. This type of block is a well -known block of aerated concrete (AAC) or as aublok of cell concrete Toclave (ACC). This type of concrete block is made of a mixture containing a binder with smaller cement portions than in a more common block and aluminum powder Aggregate along with mixing water. Although as strong as regular concrete blocks, AAC blocks are much lighter. However, the AAC block is much more expensive than the currentThe concrete block and therefore not used considerably.

The most common concrete block is a core, has two or three holes in the center of the block. This is done for many reasons. First, it reduces the weight of the block. Second, reinforcement or long steel sticks can be inserted into the core to strengthen the wall carrying a block. Thirdly, the cores in the block can be filled with sand or gravel in further progress of strengthening.

Other sizes and shapes of concrete blocks are also available for different excuses. There are notch blocks for windows and door sills and angle blocks for corners. V -blocks are also known as closing units. In addition, there are blocks of headers and bull nose. Special blocks can be obtained suitable for unique requirements of any type of masonry structure.

The blocks are also covered to ensure proper weathering and provide additional insulation for the interior of the structure.
