Since the time of the Roman empire, the world has been constantly using and perfecting concrete because it is the most chosen material in most of the commercial and residential construction projects. As we look around, most of the foundations for buildings and structures are built on concrete foundations and cemented slabs.
A cemented slab is a very common example of structural element of modern buildings which consists of a flat, horizontal surface made up of cast concrete. Steel-supported slabs are most often used to construct floors and ceilings. A thick cemented slab supported on foundations or directly on the subsoil is used to construct the ground floor in many domestic and industrial buildings. These slabs are called as ground bearing or suspended concrete slabs.
The process of construction of cemented slabs
- Cemented slabs are engaging in a good working connection with a cemented or concrete slab builder who has experience in slab construction.
- Keep in mind that before the concrete trucks can begin delivering, the site should be properly prepared. The ground should be cleared and brought to a point where the electricians and plumbers can make a foxhole and install their respective services. When these utilities are laid under where these slabs will be, then they are stubbed up above where the concrete will be poured and properly identified for other construction crews to complete their jobs once these slabs are finally placed. The concrete forms can be constructed around the perimeter of the slab when all the groundwork is finished, the slab footings can be prepared, and all the specifications must meet local codes and architectural design requirements.
- Now the bedding of the cementedslab can be placed on top of the prepared site. It is important because it will enhance the longevity of cemented or concrete slabs and provides an extra layer of protection against the cracking and breaking of the slab in several cases after the settling process begins.
- After this process, the concrete brace can be added. This will most probably in the form of re-bar which is laid in the slab site and resembles a kind of grid-like pattern. These bars will support the cemented slab for the duration of its life.
- When trucks begin their delivery, concrete will be poured into this formed area, brought flush with the tops of the forms, any specific finishes applied to the surface of the concrete before then it is allowed time to cure. Internal or external vibration will be applied to make sure the concrete is packed into every void in the formed area drawing the concrete into these areas that sometimes can go unnoticed.
- The process of curing the slab involves spraying it with water a few times every day for the first week. The purpose of this process is to make sure whether the concrete has sealed properly or not. The forms can be removed when the 24 hours have passed and the slab can be walked. But we should wait for at least 7 days before adding sufficient weight on top of the slab.
