Post tensioning – Advantages and applications

The duct resists bond among concrete and the tendons while the tensioning is goining.

Contrary to pre-tensioning, the tendons are extracted with the reaction acting against the hardened concrete.

When the arranged ducts are grouted, then it is known as bonded post-tensioning.

And when the ducts are not grouted then it is known as unbonded post-tensioning. Tendon is retained in place with end anchorages.
