A rectangular reinforced concrete structure can be described as a concrete slab. It can be cut to size and number of width and length, but not in terms of depth. It's also used to build roofs, floors, bridge decks, as well as other structures.
There are a variety of designs for making a concrete slab suspended to increase its strength as well as weight. In all cases, only the bottom surface is altered, while the top is flat.

Corrugated concrete is discharged into an inclined tray made from steel. It improves its strength as well as reduces the chance of bending the slab due to the load on its own.
- Ribbed slabs, where substantial strength increases in one direction.
- A Waffle slab, where additional strength is provided in both directions.
- One-way slabs, where the strength of the structure is stated in the direction that is the shortest.
- In a Two-way slab, in this case, the strength of the structure is shown in two directions.
The Building of Concrete Slab
The concrete slab can be prefabricated or one that is in situ. Prefabricated slabs are made in factories and then transported to the place which is where they are lowered to their location between concrete beams or steel.
It could be pre-stressed in the factory, then post-stressed on the site, or end up being unstressed. The major drawback of these slabs is that if they're not in the proper dimensions, they may not be suitable.
When it comes to in-situ construction that is, this slab of concrete is constructed on the location of the building by using an enclosure into which the wet concrete is poured. This is known as formwork.
