← ScienceWhich outcome occurs from latent heat release during rapid ice formation in concrete?
A)Accelerated cement hydration reaction
B)Delayed salt scaling propagation
C)Elevation of internal pore pressure✓
D)Reduced long-term alkali-silica reactivity
💡 Explanation
Elevated pore pressure occurs because volumetric expansion during the ice-liquid phase transition concentrates unfrozen water into diminishing spaces, resulting in cryostatic pressure rather than hydration changes. Therefore, pore pressure increases rather than scaling reduction or decreased reactivity.
