What is the purpose of bonded tendons in prestressed concrete?
Bonded tendons are used to transfer prestressing force to the concrete through frictional resistance along the tendon-concrete interface, providing structural integrity and load-carrying capacity.

See lessWhat is the purpose of grouting in post-tensioning?
Grouting fills the ducts surrounding the tendons with a cementitious material, providing corrosion protection for the tendons and ensuring effective transfer of prestressing force to the concrete.

See lessWhat are the steps involved in the post-tensioning process?
Steps include drilling ducts or sleeves into the concrete, inserting the tendons, grouting the ducts to bond the tendons to the concrete, tensioning the tendons, and anchoring them at the ends.
