N2 - Towards the development of a wireless embedded sensor system to monitor and assess corrosion damage in tendons of prestressed concrete girders, reinforced concrete specimens were manufactured with seeded defects to simulate tendon corrosion damage. These specimens with seeded defects were then tested using an acousto-ultrasonic approach by taking advantage of the waveguide effects of the reinforcing bars. Current results indicate that the loss of cross-section in the reinforcing steel can be evaluated using the proposed methodology. Furthermore, results also indicate that the loss of bond strength between the reinforcing steel and the surrounding concrete can be evaluated. Based upon this quantitative evaluation of bond loss between concrete and reinforcement and the loss of cross-section in reinforcement, the structural response degradation caused by corrosion can then be estimated.
