Method and apparatus for corrosion protection of the terminal end of a post-tensioned tendon

摘要

A post-tensioned anchor assembly having an anchor, a tendon affixed within the anchor and having an end extending outwardly from the anchor, and a cap affixed in direct electrical connection onto the tendon. The tendon is of an electrically conductive material. The cap covers the end of the tendon. The cap is made of an anodic material such as zinc or magnesium. The cap has an inner surface which matches a diameter of the tendon so that the inner surface is in surface-to-surface contact with the tendon. The cap can also be brazed to the tendon for establishing electrical contact.
