Characterization of acoustic emission features during corrosion initiation of reinforcing steel in alkaline chloride solutions

Key Points

• Corrosion initiation leads to significant acoustic emissions in reinforcing steel, indicating material degradation over time.
• Acoustic emission metrics reveal a marked increase, with several distinct frequencies monitored during testing.
• Assessment using acoustic emissions identifies specific corrosion triggers in alkaline chloride environments, enhancing monitoring techniques.
• Understanding these emissions may help predict the lifespan of reinforcing steel, though field validation is needed.
