Which long-term consequence occurs when chloride ions penetrate prestressed concrete bridge deck?

💡 Explanation

When chloride ions penetrate prestressed concrete, the electrochemical potential shifts negatively promoting pitting corrosion of the high-strength steel strands followed by hydrogen embrittlement, a process that reduces the steel's ductility and load-bearing capacity. Therefore, hydrogen embrittlement of steel strands result, rather than spalling, buckling, or damping changes, which stem from different degradation processes.
