← TechnologyWhich performance decline precipitates when excessive chloride intrusion occurs in prestressed concrete?
A)Anchorage zone steel corrosion✓
B)Aggregate matrix freeze-thaw fracturing
C)Cement hydration complete conversion
D)Subcritical crack propagation arrest
💡 Explanation
Excessive chloride intrusion causes steel corrosion at the anchorage zone because it reduces the passivating oxide layer, therefore leading to loss of prestress rather than freeze-thaw damage impacting aggregate.
