Abstract:

This final report presents the research findings of a three-year synthesis study on four topics concerning corrosion-induced durability issues in grouted post-tensioned (PT) tendons and maintenance strategies to address these issues. The topics covered are major cases of corrosion in the field, key findings of national and international laboratory studies, the current understanding of corrosion mechanisms, and maintenance strategies aimed at controlling PT tendon corrosion.

This final report is expected to be of interest to bridge engineers from Federal, State, and local transportation departments as well as to parties engaged in bridge-related research.
