Evaluation and Performance Monitoring of Corrosion Protection Provided by Fiber-Reinforced Composite Wrapping

Corrosion damage of reinforced concrete structures has become an extremely costly maintenance item in the United States. The structures affected are commonly those in or near marine environments and transportation structures on which de-icing salts are used. An increasingly popular repair method for structures in corrosive environments is the application of a fiber-reinforced composite wrap to the concrete surface. The objective of this report is to establish a field research program to analyze the effects of composite wrapping systems on the corrosion process. The research includes performance monitoring with various devices to help determine corrosion conditions before and after repair with a wrapping system.
