Impressed Current Cathodic Protection (ICCP) is a widely utilised method for safeguarding reinforced concrete (RC) structures, including bridges, in marine environments. However, certain ICCP systems encounter degradation of the backfill mortar caused by acid formation at anode. The produced reacts with anode mortar, compromising functioning cathodic protection system. Rectifying acidification issue typically involves replacing and, some cases, even when it negatively impacted attack. This...

Developments in Structural Health Monitoring (SHM) research over the past few decades have demonstrated potential optimising maintenance solutions for degrading infrastructure.
