2、 A number in parentheses indicates the year of last reapproval.A superscript epsilon () indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the Department of Defense.1. Scope*1.1 This specification covers ten types of portland ce
3、ment, as follows (see Note 2):1.1.1 Type IFor use when the special properties specified for any other type are not required.1.1.2 Type IAAir-entraining cement for the same uses as Type I, where air-entrainment is desired.1.1.3 Type IIFor general use, more especially when moderate sulfate resistance
4、is desired.1.1.4 Type IIAAir-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 aredesired.1.1.6 Type II(MH)AAir-entraining cement for the same uses as Type
5、 II(MH), where air-entrainment is desired.1.1.7 Type IIIFor use when high early strength is desired.1.1.8 Type IIIAAir-entraining cement for the same use as Type III, where air-entrainment is desired.1.1.9 Type IVFor use when a low heat of hydration is desired.1.1.10 Type VFor use when high sulfate
6、resistance is desired.NOTE 1Some cements are designated with a combined type classification, such as Type I/II, indicating that the cement meets the requirements ofthe indicated types and is being offered as suitable for use when either type is desired.NOTE 2Cement conforming to the requirements for
7、 all types are not carried in stock in some areas. In advance of specifying the use of cement otherthan 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 valu
8、es stated in eachsystem may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from thetwo systems may result in non-conformance with the standard. Values in SI units or inch-pound units shall be obtained bymeasurement in SI units or inch-poun
9、d units or by appropriate conversion, using the Rules for Conversion and Rounding givenin IEEE/ASTM SI 10, of measurements made in other units or SI units. Values are stated in only SI units when inch-pound unitsare not used in practice.1.3 The text of this standard references notes and footnotes wh
10、ich provide explanatory material. These notes and footnotes(excluding those in tables and figures) shall not be considered as requirements of the standard.2.

Ingredients5.1 The cement covered by this specification shall contain no ingredients except as follows:5.1.
22、1 Portland cement clinker.5.1.2 Water or calcium sulfate, or both. The amounts shall be such that the limits shown in Table 1 for sulfur trioxide andloss-on-ignition are not exceeded.5.1.3 Limestone. The amount shall not be more than 5.0 % by mass such that the chemical and physical requirements of
23、thisstandard are met (See Note 3). The limestone, defined in Terminology C51, shall be naturally occurring and consist of at least 70 %by mass of one or more of the mineral forms of calcium carbonate.NOTE 3The standard permits up to 5 % by mass of the final cement product to be naturally occurring,
24、finely ground limestone, but does not requirethat limestone be added to the cement. Cement without ground limestone can be specified in the contract or order.TABLE 1 Standard Composition RequirementsCement TypeAApplicableTestMethodI andIAII andIIAII(MH)andII(MH)AIII andIIIAIV VAluminum oxide (Al2O3)

The interground addition shall conform to therequirements of Specification C226.6. Chemical Composition6.1 Portland cement of each of the ten types shown in Section 1 shall c
34、onform to the respective standard chemical requirementsprescribed in Table 1. In addition, optional chemical requirements are shown in Table 2.NOTE 5The limit on the sum, C3S + 4.75C3A, in Table 1 provides control on the heat of hydration of the cement and is consistent with a Test MethodC186 7-day
35、heat of hydration limit of 335 kJ/kg 80 cal/g.NOTE 6There are cases where performance of a cement is improved with SO3in excess of the Table 1 limits in this specification. Test Method C563is one of several methods a manufacturer can use to evaluate the effect of sulfate content on cement characteri
36、stics. Whenever SO3content of a cementexceeds Table 1 limits, Test Method C1038 results provide evidence that excessive expansion does not occur at this higher sulfate content.7. Physical Properties7.1 Portland cement of each of the ten types shown in Section 1 shall conform to the respective standa
37、rd physical requirementsprescribed in Table 3. In addition, optional physical requirements are shown in Table 4.8.
