Standard Specification for Portland Cement
 N C150/C150M

Annotation

This specification covers ten types of portland cement, as follows (see Note 2)

Type I—For 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 a low heat of hydration is desired

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

NOTE 2—Cement conforming to the requirements for all types are not carried in stock in some areas. In advance of specifying the use of cement other than Type I, determine whether the proposed type of cement is, or can be made, available
