Post Tensioned Beam


Step 1
Cable ducts and reinforcement are positioned in the beam mould as shown in picture.

Step 2
Concrete is cast into the beam mould and allowed to cure to the required initial strength.

Step 3
Tendons are threaded through the cable ducts and tensioned to about 75% of their ultimate strength.

Step 4
Wedges are inserted into the end anchorages and the tensioning force on the tendons is released. Grout is then pumped into the ducts to protect the tendons.
