Calcium sulfate (CaSO4) is added to cement to control this high-reactivity component (SO3 as indicated on the mill certificate). C3A is not limited in Type I cement, so when a producer labels a cement mill certificate as "Type I/II" it really means it is a Type II cement that also meets the Type I requirements.
