What is pre tensioning and post tensioning in pre stressed concrete

Pre-Tensioning in Prestressed Concrete The Pre-stressed Concrete Institute (PCI) defines Pre-Stressing as “the application of a force to the reinforcing steel in concrete, so that it is loaded and unloaded periodically, to develop tensile stresses in the steel. The periodic loading produces compressive stresses which resist cracking.” Pre-tensioning is done by pulling or tightening cables
