Which outcome occurs when excessive chloride ions permeate concrete around a prestressed steel cable.?

💡 Explanation

When chloride ions permeate concrete, they cause pitting corrosion of the prestressed steel, leading to hydrogen embrittlement because corrosion weakens steel and absorbed hydrogen reduces cracking resistance. Therefore brittle fracture results, rather than spalling, reactions requires different agents (sulfates, reactive silica) and mechanisms.
