Type II—This cement possesses moderate resistance to sulfate attack because of certain limitations on composition. Sometimes called moderate-heat cement, it is intermediate between Type I and the low-heat Type IV cement. If moderate heat of hydration is desired, however, the optional limit on heat of hydration should be invoked when specifying or ordering.

- Type III—High-early-strength portland cement is often produced by grinding Type I clinker finer or by altering the chemical composition of the cement.

- Type IV—Low-heat portland cement. Not currently made in the United States and limited in production elsewhere.

- Type V—Sulfate-resisting portland cement with appropriate limits on composition.

In addition, portland cement can also be specified under ASTM C1157 (Standard Performance Specification for Hydraulic Cement) as:

- Type GU—general use.

- Type HE— high early strength.

- Type MS—moderate sulfate resistance.

- Type HS—high sulfate resistance.

- Type MH—moderate heat of hydration.

- Type LH—low heat of hydration.
