Difference Between Pre Tensioning and Post Tensioning

A tendon is generally made of wires strands or bars Wires and strands can be tensioned in groups whereas bars are tensioned one at a time In the post tensioning process the steel tendons are placed in the formwork before the concrete is cast and the tendons are prevented from bonding to the concrete by waterproof paper wrapping or a metal duct sheath
