← TechnologyWhich risk increases when epoxy-bonded carbon fiber reinforcement is improperly applied to a concrete beam?
A)Premature concrete spalling due to thermal expansion
B)Corrosion acceleration of internal steel reinforcement
C)Debonding failure at the adhesive interface✓
D)Beam buckling from compressive stress increase
💡 Explanation
When epoxy-bonded carbon fiber reinforcement is improperly applied, adhesion fails because surface preparation isn't sufficient or incorrect epoxy mixture, leading to stress concentration. Therefore debonding failure results, rather than spalling, corrosion, or buckling, which occur under different loading scenarios like freeze-thaw cycles or excessive loading.
