Corrosion Evaluation of Post-Tensioned Tendons Embedded in Concrete Bridges
Project Information
Project ID:
FHWA-PROJ-08-0070
Project Abstract:
The Coatings and Corrosion Laboratory at Turner-Fairbank Highway Research Center of the Federal Highway Administration launched an in-house corrosion study addressing a very critical durability issue related to post-tensioned concrete bridges. Currently, there are no effective nondestructive corrosion detection techniques to diagnose corrosion activities hidden inside post-tensioned tendons despite a growing number of this type of bridge structure. Accelerated corrosion testing is being conducted with five 4-inch diameter and 7-10 ft. field tendons and two mockup laboratory specimens. Condition of the deteriorated tendon specimens will be assessed in terms of section loss and extent of corrosion by several experimental techniques such as Magnetic Flux Leakage (MFL) and other nondestructive evaluation (NDE) methods. Reliable NDE technique(s) with accuracy and reproducibility will be identified at the end of the study.
