What is post-tensioning?

Post-tensioning is a method of reinforcing concrete. High-strength steel tendons are positioned in ducts or sleeves before the concrete id placed. Once the concrete has gained strength, tension is then applied, pulling the tendons and anchoring them against the outer edges of the concrete, before service loads are applied.

The PT technique is a form of pre-stressing, which differs slightly from post-tensioning as steel tendons are tensioned before the concrete is placed. The tendons are strentched between strong builheads which withstand external forces and the concrete is poured around them.
