← TechnologyWhich risk increases when column formwork is prematurely removed from freshly poured concrete?
A)Buckling due to insufficient strength✓
B)Corrosion due to increased surface area
C)Spalling due to rapid hydration
D)Creep due to uneven stress distribution
💡 Explanation
When formwork is prematurely removed, insufficient concrete curing leads to inadequate compressive strength because the hydration process arrests, thus reducing resistance to axial loads. Therefore, buckling risk increases rather than corrosion, spalling, or creep which involve different long-term degradation mechanisms.
