Standard concrete floor slab thickness in residential construction is 4 inches. Five to six inches is recommended if the concrete will receive occasional heavy loads, such as motor homes or garbage trucks.
How Thick Concrete Slab?
A concrete slab is a flat, horizontal surface made of concrete. It can be used as a floor, a base for a wall, or a roof. The thickness of a concrete slab is usually 4 to 12 inches (100 to 300 mm).
The thickness of a concrete slab depends on its purpose. For example, a floor slab in a office building is usually 4 to 6 inches (100 to 150 mm) thick. A roof slab in a warehouse is usually 8 to 12 inches (200 to 300 mm) thick.
A concrete slab is made of concrete, which is a mixture of cement, sand, gravel, and water. The concrete is poured into a mold, and then it is left to harden.
The concrete slab can be either cast–in–place or precast. Cast–in–place concrete slabs are poured directly on the ground. The ground must be level and well–compacted.
The concrete must be placed in the mold in one continuous pour. Precast concrete slabs are made in a factory. They are cast on a bed of sand.
The concrete is placed in the mold and then it is left to harden. The precast concrete slabs are then transported to the job site and lifted
