Which consequence results when differential heating destabilizes concrete?

A)Reduced compressive strength occurs earlier
B)Increased chloride diffusion accelerates corrosion
C)Increased silica polymerization spontaneously generates heat
D)Leaching produces expansive hydration products

💡 Explanation

Increased chloride diffusion occurs, because ionic conductivity increases within the porous concrete matrix during thermal cycling; therefore corrosion risk increases, rather than hydration or material changes because chloride is the corrosive agent.
