Abstract:
The 1980s revealed considerable increase of damages on concrete bridges due to chloride-induced corrosion. A major part of these concrete bridges were designed with post-tensioning cables as an essential part of the structure. Normally, these tendons are regarded as well-protected against deterioration, as they are placed in injected cable ducts relatively far from the exposed surface. However, the experience of the durability of concrete structures has revealed that corrosion and damage of the tendons can occur.
