← ScienceWhich consequence results when rapid hydration of calcium aluminate cements induces a premature phase transition?
A)Reduced material structural integrity✓
B)Increased heat transfer coefficient
C)Enhanced electrical conductivity
D)Improved acoustic damping properties
💡 Explanation
Rapid hydration forms unstable hydrates that then convert via phase transition (conversion) to weaker forms, because this process reduces the cohesive forces between cement particles. Therefore, the structural integrity reduces, rather than it improving other physical properties.
