Prestressed concrete From Wikipedia, the free encyclopedia Prestressed concrete is a method for overcoming concrete's natural weakness in tension. It can be used to produce beams, floors or bridges with a longer span than is practical with ordinary reinforced concrete.

Applications. Prestressed concrete is the main material for floors in high-rise buildings and the entire containment vessels of nuclear reactors.. Unbonded post-tensioning tendons are commonly used in parking garages as barrier cable. [3] Also, due to its ability to be stressed and then de-stressed, it can be used to temporarily repair a damaged building by holding up a …

Concrete and Concreting, Prestressed Concrete, concrete in construction. Pre tensioned concrete is a different ball game and it usually applies to work done in specialised casting factories with the enormously strong jacking points and the safety measures in place in case of cable failure.

External prestressing is a kind of postprestressing method, in which prestressing tendons are located outside the concrete section and the prestressing force is transferred to a structural member through end anchorages or deviators, as shown in Fig. 6.8.There are many advantages of this method, such as easy in concrete casting, thus better concrete quality, allows easy …
