Corrosion rate significantly affects acoustic emission characteristics of reinforced concrete, especially early on.
Increased corrosion from 5 to 15 V advanced cumulative AE energy change time by 2 days.
Utilizing acoustic emission, a model predicts concrete bridge damage risk linked to corrosion and durability.
Highlights importance of monitoring corrosion to improve maintenance strategies for highway bridges.
