← TechnologyWhich 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.
