State the method of Pre- Tensioning
It is a method of prestressing concrete in which tendons are stretched or tensioned before concreting. In this form of construction, concrete develops a bond with the surface of stretched tendons. When sufficient bond strength is developed in concrete so as to retain stretched tendons in their tensioned form, tendons are cut from outside. The inside embedded length of tendons keeps its stretched form inside concrete due to bond and the prestressing force is maintained inside concrete.
