Abstract:

Acoustic emission monitoring was performed in a unique way on concrete specimens containing reinforcing steel and the acoustic emission events correlated with the presence of rebar corrosion. Verification of rebar corrosion was done by galvanic current, half-cell potential, and electrochemical analysis. Results showing the early onset of rebar corrosion from acoustic emission are presented.
