Which risk increases when concrete's rebar bonding fails?

A)Accelerated aggregate degradation
B)Premature structural collapse
C)Elevated creep deformation
D)Reduced thermal expansion

💡 Explanation

Premature spalling occurs because loss of interfacial shear transfer causes concentrated stress. Therefore, structural integrity is compromised, ultimately leading to potential collapse rather than localized degradation that redistributed stresses would accommodate.
