Which outcome results when concrete cover over rebar is insufficient in marine environment?

💡 Explanation

When concrete cover is insufficient in a marine environment, chloride ions diffuse through the concrete because the protective layer is thin, causing corrosion of the steel rebar. Therefore, accelerated rebar corrosion occurs, rather than reduced compressive/tensile strength or increased creep which involve different deterioration mechanisms.
