Which risk elevates when hydraulic jacks overload supporting concrete columns during bridge maintenance?

A)Increased creep under sustained load
B)Reduced chloride diffusion resistance
C)Elevated carbonation reaction rates
D)Accelerated thermal expansion mismatch

💡 Explanation

Increased creep occurs because hydraulic overload induces sustained stress on the concrete columns, activating the mechanism of time-dependent deformation due to viscous flow of the cement matrix. Therefore, excessive deformation results, rather than changes in chloride, carbonation, or thermal properties.
