A new guided wave-based technique for corrosion monitoring

Corrosion affects the bonding strength between concrete and reinforcing steel altering the stress level in the reinforcing steel bar in a loaded beam. Since the wave speed is affected by the internal stress, an increase in corrosion level should affect the wave speed in a steel bar and the wave's time of flight through the bar.

Corrosion Rate | American Galvanizers Association

Approximately 85% of all steel produced is carbon steel and therefore susceptible to natural oxidation and galvanic corrosion. The rate of corrosion is well understood in typical atmospheric conditions, but for the design engineer, the precise localized or micro-environment conditions must be well understood for him/her to have confidence in the ultimate durability of the design.
