**What is Prestressed Concrete ?**

Prestressed Concrete is basically concrete in which internal stresses of a suitable magnitude and distribution are introduced so that the stresses resulting from external loads are counteracted to a desired degress.

Prestressed concrete is a modified form of reinforced concrete, it not only eliminates the weakness of concrete, but also makes it possible to take full advantage of compressive strength of concrete. In reinforced concrete members, the pre-stress is commonly introduced by tensioning the steel reinforcement.

In addition to structural precast members, viz., joists, beams, slabs, columns, girders, etc, prestressed concrete is used for the framed multi-storeyed buildings. Prestressed concrete can be applied to almost all concrete constructions where ordinary reinforced concrete is used. But due to high cost or prestressing and better quality materials used, its use is made under special condition, particularly for precast members.

A large variety of industrial structures such as silos, roof trusses, water tanks, piles, pipes, nuclear power stations, factories, steel plants, electric sub-stations, etc can also be built in prestressed concrete.
