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

1.1.1 Type I8212;For use when the special properties specified for any other type are not required.

1.1.2 Type IA8212;Air-entraining cement for the same uses as Type I, where air-entrainment is desired.

1.1.3 Type II8212;For general use, more especially when moderate sulfate resistance is desired.

1.1.4 Type IIA8212;Air-entraining cement for the same uses as Type II, where air-entrainment is desired.

1.1.5 Type II(MH)8212;For general use, more especially when moderate heat of hydration and moderate sulfate resistance are desired.

1.1.6 Type II(MH)A8212;Air-entraining cement for the same uses as Type II(MH), where air-entrainment is desired.

1.1.7 Type III8212;For use when high early strength is desired.

1.1.8 Type IIIA8212;Air-entraining cement for the same use as Type III, where air-entrainment is desired.

1.1.9 Type IV8212;For use when a low heat of hydration is desired.

1.1.10 Type V8212;For use when high sulfate resistance is desired.

Note 18212;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 28212;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.

1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard. Values in SI units [or inch-pound units] shall be obtained by measurement in SI units [or inch-pound units] or by appropriate conversion, using the Rules for Conversion and Rounding given in IEEE/ASTM SI 10, of measurements made in other units [or SI units]. Values are stated in only SI units when inch-pound units are not used in practice.

1.3 The text of this standard references notes and footnotes which provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the standard.
