Which risk increases substantially when improper concrete curing reduces hydration within prestressed concrete beams used in bridge construction?

A)Reduced long-term creep resistance

B)Increased susceptibility to chloride ingress

C)Compromised bond strength of steel✓

D)Accelerated fatigue crack propagation

💡 Explanation

Compromised bond strength increases dramatically because decreased hydration impairs cement matrix development around prestressing strands, inhibiting effective stress transfer via interfacial adhesion rather than resisting environmental chloride intrusion; therefore correct answer is C.
