![]() ![]() This is a special type of block that can use used to construct the partition walls. They are used to construct the corners or the ends of the block walls. The placement of the blocks is the same as the other types of concrete hollow blocks. The most widely used type of hollow blocks and are used to joint the corners. There are different types of hollow blocks. These types of concrete blocks are readily available in any market and they can be made easier with modern equipment in a shorter period of time. and those holes can also be used to carry the services such as electrical conduits, pipes, etc. Hollow Concrete BlocksĪs discussed above, hollow blocks are more popular in building construction due to the many advantages brought to the project.ĭue to the hollow shapes, it reduces the heat transfer, works as a sound barrier, etc. However, there are many types of concrete blocks made as hollow blocks. There is no much to discuss the types of solid blocks. Less weight, less coss, less cost of the structure, etc have made the use of this type of hollow block. They are also available in the same widths as solid blocks. Usually, they are available in widths 100mm, 125mm, 150mm, and 200mm.Īs the name implies, it is a hollow section with a regular shape. Normally blocks have a rectangular solid shape. Mainly there are two types of concrete blocks depending on how they look like other than the mechanical properties. The minimum compressive strength of non-load bearing blocks could be maintained greater than 7.5 N/mm 2 and load-bearing walls 12.5 N/mm 2. Mechanical mixing can be done to get a consistent mix. Select the materials according to the to mix propositions.In summary, the following steps can be highlighted as the manufacturing process of the concrete blocks. Further, better and consistent compaction can be achieved through the machine. Further, depending on the capacity of the machine, we can make many blocks at once. However, when the machine is used, it quite easy and we can achieve good results. This method is time-consuming and even quality control is very difficult.įurther, it is very difficult to maintain consistency when it is done manually. In the conventional method, we do the mixing and put into the mold, and when it is completed. Mainly we used crushed stone, gravel, volcanic cinders, foamed slag, furnace clinker, etc.Īggregates shall be checked regularly to assess the conditions and it shall be made sure they are within the approved gradation. Various types of aggregates can be used in block production. Let’s see what are the material to be used Quality control can be done without much difficulty when we used machines for production. Not like the old days, we have machines to make the blocks much easier. Widely used for cavity walls construction.Ĭoncrete blocks shall be manufactured in accordance with BS EN 771: part 3 and they shall be checked in accordance with BS EN 772.Used as formwork for pile caps, ground beams, etc.Used to construct partition walls, perimeter walls, etc in the building construction.Let’s list the major application of the theme. In construction, today, we can see the wide use of concrete blocks in the construction. Further, the ability to use minimum thickness for plastering and wastage of material, really availability, speedy construction, etc has made the concrete blocks more popular in the construction industry. Further, it as adequate strength to used a load-bearing wall. It is comparatively more economical than the other types of partition walls.Ĭoncrete blocks have a comparatively good shape and the change of making error during construction is minimal. Concrete blocks are widely used in building construction. ![]()
