Which risk increases when concrete pour timing exceeds rebar's 'flash rust' passivation?

💡 Explanation

Compromised bond strength increases because flash rust converts the rebar surface, using hydrogen embrittlement as the mechanism. This reduces adhesion, therefore weaker composite action occurs, rather than chloride resistance, thermal stress, or reduced compression, which are separate concerns.
