Reinforced Concrete Slab
Every modern building has concrete slabs. Builders use the reinforced concrete slab for ceilings and floors. They use them for exterior paving as well. Mostly, the concrete slabs used for paving are thinner than the ones that constructors use to build ceilings and floors. Builders use concrete slabs that have 10 to 50 cm thickness for ceiling and floors. When making large industrial and commercial buildings, constructors put concrete slabs for the floor with the aid of foundations or on soil. When building multi-stories building, constructors use precast concrete slabs reinforced with steel frames for the base floor as well as for other floors.
The abbreviation for Reinforced Concrete Slab in the construction field is ‘R.C’ or ‘R.C. slab’. In the past, concrete slabs were poured on the soil. Nevertheless, with modern structures, special measures are taken to prevent heating problems. Rather than putting concrete directly on the soil, constructors now put concrete on a layer that has insulation techniques underneath such as expanded polystyrene and pipes designed for draining heating. However, you may still find constructions that have plain slabs at places where the temperature is cool.
Builders use many methods to produce a reinforced concrete slab. Some pour concrete to corrugated steel frames. Reinforcement plates, fibers, grids etc are also used to reinforce concrete. The reinforced concrete slab with iron or steel is called Ferro Concrete. Other than these, manufacturers use organic as well as inorganic fibers and composites in many degrees for reinforcement of concrete. Although concrete have greater compression ability than other materials, it is weak in tension. Because of this, it may crack in many places after sometime. Reinforcement method is greatly helpful to stop the cracking of concrete.
Reinforcing of concrete enhances its strength, and it has great tension resistant ability as well. Reinforcement also bonds concrete preventing cracks and it gives solution for the heating problems as well. Most of all a reinforced concrete slab is durable than others. However, you cannot use steel reinforced concrete for some buildings. Especially buildings where MRI machines are to be located, constructors use nonmagnetic materials.
Many builders use corrosion proof reinforced concrete. This type of reinforced concrete slab is made with fiber plastics. Plastic reinforced concrete slab is lighter than steel ones. Steel reinforced concrete has an outer layer about 30 to 50 mm thick whereas plastic reinforced concrete has no such layers. In addition to lightness, it is inexpensive and has a long life span, as it is corrosion resistant. Using reinforced concrete slabs greatly enhances the strength of buildings. It is cost effective and enhances the durability of buildings as well.
