Define the term - pre- tensioning

It is a method of prestressing in which tendons are placed, inside ducts or passages provided in concrete, after concrete gains sufficient strength. Tendons are then stretched and anchored at the ends of the concrete member. The transfer mechanism of prestressing force in this form of prestressing is different from that in the case of pre-tensioning. In this form of prestressing, the prestressing force is transferred to concrete through anchorages provided at the ends - not due to bond between concrete and tendons.
