← TechnologyWhich failure outcome arises when ultrasonic inspection misses voids in prestressed concrete bridge beams?
A)Accelerated steel tendon corrosion✓
B)Compromised aggregate interlock capacity
C)Reduced concrete compressive strength
D)Increased long-term creep deflection
💡 Explanation
Unidentified voids permit moisture ingress leading to chloride-induced corrosion; hence the **galvanic corrosion** undermines tendon integrity because it reduces cross-sectional area of said steel, therefore weakening the prestressing rather than affecting bulk concrete properties
