Corrosion of steel reinforcement in carbon fiber-reinforced polymer wrapped concrete cylinders
This paper investigates the use of carbon fiber reinforced polymer (CFRP) composite wraps to provide protection for, or delay the onset of corrosion in reinforced concrete specimens exposed to aggressive chloride environments. Additionallly, the effects of fabric orientation, number of wrap layers, and the type of epoxy are considered. Results from this study indicate that carbon fiber-reinforced polymer wraps increase a reinforced concrete sample's resistance to accelerated corrosion in a submerged environment as evidenced by prolonged life, lower corrosion potential, decreased overall rate of reinforcement mass loss, and reduced concrete chloride content. The type of epoxy used as a surface treatment has a significant effect on the corrosion resistance. Samples with FRP wraps performed better tha samples coated only with epoxy, while epoxy coating alone was not beneficial. Increasing the number of wraps from one to two proved to be effective however, three wrap layers was not clearly shown to be more effective than two wrap layers. The wrap fiber orientation was also shown to affect the corrosion performance. The best results occurred when the fiber strong axis was aligned radially, in the direction of maximum possible confinement.
