Standard Specification for Portland Cement

This specification covers eight types of portland cement, as follows (see Note 1): 1.1.1 Type I -For use when the special properties specified for any other type are not required. 1.1.2 Type IA -Air-entraining cement for the same uses as Type I, where air-entrainment is desired. 1.1.3 Type II -For general use, more especially when moderate sulfate resistance or moderate heat of hydration is desired. 1.1.4 Type IIA -Air-entraining cement for the same uses as Type II, where air-entrainment is desired. 1.1.5 Type III -For use when high early strength is desired. 1.1.6 Type IIIA -Air-entraining cement for the same use as Type III, where air-entrainment is desired. 1.1.7 Type IV -For use when a low heat of hydration is desired. 1.1.8 Type V -For use when high sulfate resistance is desired. 1.2 When both SI and inch-pound units are present, the SI units are the standard. The inch-pound units are approximations listed for information only.
