This specification covers ten types of portland cement as follows (see Note 1):

Type I—For general use, when the special properties specified for any other type are not required;
Type IA—Air-entraining cement for the same uses as Type I, where air entrainment is desired;
Type II—For general use, more especially when moderate sulfate resistance is desired;
Type IIA—Air-entraining cement for the same uses as Type II, where air entrainment is desired;
Type II(MH)—For general use, more especially when moderate heat of hydration and moderate sulfate resistance are desired;
Type II(MH)A—Air-entraining cement for the same uses as Type II(MH), where air entrainment is desired;
Type III—For use when high early strength is desired;
Type IIIA—Air-entraining cement for the same use as Type III, where air entrainment is desired;
Type IV—For use when low heat of hydration is desired; and
Type V—For use when high sulfate resistance is desired.

Note 1—Some cements are designated with a combined type classification, such as Type I/II, indicating that the cement meets the requirements of the indicated types and is being offered as suitable for use when either type is desired.
