← TechnologyWhich risk escalates during concrete pouring on hot days?
A)Premature rebar corrosion initiation✓
B)Increased concrete slump retention
C)Enhanced steel-concrete bond strength
D)Lower concrete permeability development
💡 Explanation
Rebar corrosion risk increases due to accelerated moisture evaporation, because this drives an increased concentration of chloride ions at the rebar surface, facilitating electrochemical reactions and pit formation. Therefore premature bar corrosion, rather than improved characteristics, occurs because of a more corrosive environment.
