← ScienceWhich 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.
