PRESTRESSED CONCRETE PRINCIPLE – Using high tensile strength steel alloys producing permanent pre- compression in areas subjected to Tension.
{"Image DocumentName": "PRESTRESSED CONCRETEPRINCIPLE \u2013 Using high tensile strength steel alloys producing permanent pre- compression in areas subjected to Tension.", "Image ImageDescription": "A portion of tensile stress is counteracted thereby reducing the cross-sectional area of the steel reinforcement . METHODS :- a) Pretensioning b)Post-tensioning. PRETENSIONING :- Placing of concrete around reinforcing tendons that have been stressed to the desired degree. POST-TENSIONING :- Reinforcing tendons are stretched by jacks whilst keeping them in serted in voids left pre-hand during curing of concrete. These spaces are then pumped full of grout to bond steel tightly to the concrete.
