Which structural failure is accelerated when chlorides permeate reinforced concrete beams supporting coastal bridges?

💡 Explanation

When chlorides permeate reinforced concrete, depassivation occurs because chloride ions break down the protective oxide layer on the steel rebar, accelerating corrosion. Therefore corrosion-induced concrete spalling results, rather than other failure modes like buckling, ASR, or creep rupture, which depend on different chemical or mechanical loading conditions.
