Portland Cement

Type I

This is a general-purpose cement that is suitable for all uses where the special properties of other types of Portland cement are not required.

Type IA

Same as Type I except an air entraining admixture has been added during the manufacturing process. Used to assist in creating durability in environments where freeze thaw cycles exist.

Type II

Has moderate sulfate resistance properties and moderate heat of hydration properties. Used when the referenced properties are desired.

Type III

Provides higher strengths at an earlier age as compared to Type I. Type III is very similar to Type I, except it is ground finer, making it more reactive. Type III Portland cement is useful when quick form turn- around times are necessary.
