Difference between Pretension and Post Tension

Post-tensioning and Pre-tensioning the two techniques are utilized in/under pre-stressing procedure which has a small number of peripheries above the conventional non-stressed structures such as higher span to depth ratio, greater shear capacity and moment.

Such techniques are usually implemented in the formation of sleepers, PSC girders, and more.

Pre–Tensioning:

• In such technique the concrete is pre-stressed with tendons prior to it is positioning in place.
• This technique is created because of bonding among the concrete as well as steel tendons.
• Pre tensioning is favored at the time the structural element is slight as well as conveniently and easily transportable.
• In such technique alike prestressed members are set/made/prepared.
• Pre-tensioning members are created in mould.

Post–Tensioning:

• In such technique prestressing is carried out once the concrete gets it’s strength.

• The technique is created/developed because of bearing.
• Post tensioning is favored at the time the structural element is weighty/heavy.
• In such technique products are altered in accordance with structure.
• Cables are utilized instead of jacks and wires are utilized for stretching.
