← ScienceWhich failure accelerates when chloride ions breach concrete?
A)Reinforcement steel's yield strength decreases
B)Concrete experiences increased freeze-thaw spalling
C)Chloride-induced corrosion accelerates significantly✓
D)Concrete's compressive strength sharply declines
💡 Explanation
Chloride ions promote **pitting corrosion** in steel reinforcement inside concrete. This occurs because the chloride ions disrupt the passive layer, therefore highly-localized corrosion happens, rather than uniform loss of material typically
