Which consequence results from excessive hydration of cement?

A)Formation of expansive sulfate phases
B)Reduced carbonation penetration rate
C)Accelerated chloride ion diffusion
D)Increased resistance to freeze-thaw

💡 Explanation

Excessive hydration causes an increase in hydroxide ions resulting in the precipitation of calcium hydroxide and leading to the **formation of expansive sulfate phases**, because the ettringite structure is destabilized. Therefore, expansion and cracking occur, rather than improved durability.
