The effective evaluation and management of corrosion in unbonded post-tensioned tendons requires an understanding of the causes of corrosion as well as an appreciation of the measures required to mitigate future corrosion. Present evaluation methods have been unsuccessful in accurately assessing the existing condition of post-tensioned structures. Continuous monitoring technology allows engineers to locate future failures so that property owners can implement cost-effective management strategies. An acoustic monitoring system, SoundPrint® has been developed which allows continuous monitoring of entire structures.
