The performance characteristics of cement are directly related to its phase composition. For example, ASTM type III cement develops high early strength and is characterized by having a larger mass fraction of alite. In comparison, ASTM type IV cement is known to have a low heat of hydration and is characterized by having a much lower mass fraction of alite
