What is Concrete Slab?
Concrete slab, which is a very popular and essential structural feature, is designed to provide functional, flat surfaces. It is a horizontal structural component, with parallel or near the parallel top and bottom surfaces.
A thick concrete slab, placed on pillars or directly on the subsoil, is used for the construction of the ground floor in many residential and industrial buildings. In fact, such slabs are known as ground-bearing or suspended. If a slab sits squarely on the base, it is ground-bearing, otherwise, the slab is suspended.
- Beam and pin, also known as rib and stack, are used mostly for residential and industrial applications. Each form of slab comprises of pre-stressed beams and hollow blocks and is propped up temporarily until finished, usually after 21 days.
- A hollow cement slab that is prefabricated and assembled on-site with a crane In high-rise buildings and skyscrapers, smaller, prefabricated concrete slabs are slung between the steel frames to shape the floors and ceilings at each level. For high elevation buildings and large shopping malls as well as homes, cast for-situ slabs are used. These in-situ slabs are made with shutters and strengthened steel on site.
Concrete Slab Support
- Masonry, or stone-lined Doors.
- Monolithically casted steel panels for the support.
- Members of Structural Steel.
- Columns The Top.
Concrete Slab Construction
Concrete floor slabs may be pre-fabricated or in situ. The concrete slab floor is built in situ using formwork, usually consisting of wooden planks & frames, plastic or steel. Ground slabs do not usually require some form-work.
Concrete Slab Reinforcement
Slab strengthening steel is primarily parallel to the surface of the slab. Straight bar reinforcement is usually used, although alternate cranked bars are sometimes used.
