← TechnologyWhich issue arises in reinforced concrete columns when using excessive rebar density?
A)Reduced concrete hydration rate internally
B)Increased susceptibility to alkali-silica reaction
C)Impaired concrete consolidation and voids✓
D)Enhanced thermal expansion mismatch stresses
💡 Explanation
When using excessive rebar, impaired concrete consolidation occurs because the dense reinforcement obstructs proper flow and compaction during placement, leading to voids. Therefore concrete consolidation is impacted, rather than hydration delay, alkali-silica, or thermal mismatch, which arise from distinct chemical or environmental conditions.
