Abstract
Highway bridge components, such as decks and piers, are structures that are often exposed to chlorine-heavy chemicals. Corrosion of rebar, one of the main contributors to structural deficiencies in highway bridges, is largely caused by chloride contamination from exposure to deicing salts and chemicals. Current forms of external protection to highway bridge piers include paint coatings, shells, and wraps. This thesis will focus on the protective capabilities that Fiber Reinforced Polymer (FRP) wraps could provide to bridge piers. ASTM C666 was utilized to recreate environmental conditions, during which concrete samples were exposed to calcium chloride. ASTM C1760-12 was utilized to determine the bulk electrical conductivity of samples exposed and not exposed to calcium chloride, in order to overall evaluate the protection that the wraps provided to the concrete samples. Overall, tests showed that unexposed GFRP wrap provided a slight layer of protection to the concrete. However, exposed FRP wraps did not provide protection to the concrete, and in some cases, even caused a reduction in resistivity of the concrete.
