Standard Specification for

Portland Cement

AASHTO Designation: M 85-15

ASTM Designation: C150/C150M-15

American Association of State Highway and Transportation Officials

TS-3a M 85-1 AASHTO

Standard Specification for

Portland Cement

AASHTO Designation: M 85-15

ASTM Designation: C150/C150M-15

1. SCOPE

1.1. This specification covers ten 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 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 II(MH)—For general use, more especially when moderate heat of hydration and moderate

sulfate resistance are desired.

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

desired.

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

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

1.1.9. Type IV—For use when low heat of hydration is desired; and

1.1.10. 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.

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.

1.3. The text of this standard references notes and footnotes that provide explanatory material. These

notes and footnotes (excluding those in tables and figures) shall not be considered as requirements

of the standard.

3. TERMINOLOGY

3.1. Definitions:

3.1.1. portland cement—a hydraulic cement produced by pulverizing clinker, consisting essentially of

hydraulic calcium silicates, and usually containing one or more of the following:

 water,

 calcium sulfate,

 up to 5 percent limestone, and

 processing additions.

3.1.2. air-entraining portland cement—a portland cement containing an interground air-entraining

addition.

3.1.3. hydraulic cement—a cement that sets and hardens by chemical interaction with water and is

capable of doing so under water.
