Abstract
Reinforced concrete is widely used as a construction material known for its durability and proficiency of withstanding large forces in severe environments. Despite that the majority of these structures result in long-term performance, there is still a large number of failures of reinforced concrete structures as a result in corrosion of the reinforcement and concrete degradation. It is critical to assess the state of the corroded structure to decide on whether maintaining or replacing the structure is needed. The objective of this study is to characterize a relationship between the steel reinforcement corrosion and the concrete's resistivity. It is widely accepted that the corrosion rate increases with decreasing concrete resistivity under common environmental exposure conditions except of those structures submerged in water. To evaluate the corrosion measurements of the reinforcement, Linear Polarization Resistance and Tafel were used to assess the accelerated tests with a current supply coupled with the concrete's surface resistivity. The research work presented in this Thesis was performed on Portland cement carbon steel reinforced concrete specimens under accelerated testing exposed to different environment conditions and concrete mixes.
