Ultrasonic Wave based Monitoring and Imaging of Civil Infrastructure

Abstract

Australian infrastructure which is predominantly close to the coast are at risk of corrosion. The prevalent visual monitoring of infrastructure warrant alleviation. Ultrasonic waves rely on interaction of waves with the substrate structure. In reinforced concrete infrastructure, they can travel through embedded rebar or surrounding concrete. Processing these wave have revealed their traits. Representative images coalescing these waves are developed. A synergistic wave based monitoring scheme through rebar and concrete is presented to disseminate corrosion.
