← TechnologyWhich outcome occurs when column concrete lacks sufficient vibration during pouring?
A)Increased risk of rebar corrosion✓
B)Delayed concrete hydration process
C)Compromised aggregate interlock strength
D)Elevated alkali-silica reaction rate
💡 Explanation
Rebar corrosion risk increases due to honeycombing which occurs when insufficient vibration prevents proper consolidation. This inadequate compaction leads to voids around the rebar, allowing moisture and chlorides to penetrate because the protection from the concrete's high alkalinity is reduced, rather than delayed hydration.
