Which failure mode increases with prolonged exposure to chlorides in reinforced concrete beams supporting a marine pier?

💡 Explanation

Chloride-induced corrosion weakens the steel rebar because chlorides penetrate the concrete, disrupt the passive oxide layer, therefore accelerating oxidation of the steel, rather than physical expansion, which are alkali-silica reaction or freeze thaw cycles.
