Which risk increases when cathodic protection fails for rebar in a coastal concrete bridge pier?

💡 Explanation

When cathodic protection fails, the electrochemical potential difference between rebar and the environment is no longer maintained, leading to accelerated chloride-induced corrosion due to increased ion migration at the steel surface. Therefore accelerated corrosion results, rather than carbonation, compressive strength reduction, or load capacity decrease, which are consequences of different degradation processes.
