The prestress concrete technology was developed to make concrete section of smaller size which can effectively resist the bending stresses developed due to heavy loads on it, but in earlier practice, it is now being an application to make long span bridges without any risk of failure. The prestressing technique is now used widely in construction industry for making long span bridges, large span slabs, Railway sleepers, precast pavements etc.
As we commonly seen that this prestressing has been done in Girders (Which resists the Transverse Moving loads) of a bridge, act as a beam for deck slab of a bridge, but in recent practice, we have seen that the small block of slabs with ducts, which are further prestress, can also be made which we can be used to resist the loads (or we can say the bending stresses) effectively which will further help us to reduce the number of girders and also it will lead to reduce the erection problems as they are precast units so it can anchored easily and it will not affect the traffic flow along the construction work.
