Difference between pre tensioning and post tensioning
v Pre Tensioning Vs Post Tensioning:-Pre-tensioning and post-tensioning are both methods of pre stressing concrete, which involves reinforcing concrete with steel tendons . ü Pre tensioning vs post tensioning When tendons are tensioned before concretes are poured is called pre tensioning. When tendons are tensioned after concretes are hardened is called post tensioning. It is good for precast construction . It is good for long span and high structural efficiency. Steel is mostly stay horizontal. Steel wires can be placed any desired profile. § Work Function:- 1) In pre tensioning steel tendons are stressed before concrete is poured around them. 2) In post tensioning the steel tendons are inserted in void in cured concrete using jacks.the jacks are replaced with permanent anchorages . o Benef...
