Corrosion Prevention of Bridge Tendons using Flexible Filler Materials

One objective is to prepare a literature review of flexible filler materials that are used in Post-Tension (PT) system applications or are used on similar applications. The review will also identify cases in which corrosion took place in service and in lab experiments. A second objective is to identify the mechanisms that provide corrosion protection. A third objective is to identify tests to characterize these fillers for compliance with requirements (from a corrosion protection standpoint). Additionally, tests will be identified to assess situations that potentially could cause corrosion. There is a need to be proactive and learn if outdoor exposure could potentially degrade/contaminate the flexible fillers. If that is the case, procedures could be required that prevent/minimize degradation/contamination. In addition, the effects of overheating and reheating the flexible filler materials will be studied. As the Department moves to use these flexible fillers, there is a need to know if corrosion could be possible and under what conditions, rather than finding out corrosion of the steel strands during service.
