A number i
2、n parentheses indicates the year of last reapproval.A superscript epsilon () indicates an editorial change since the last revision or reapproval.1 NOTERevised editorially to remove an erroneous reference in 9.1.7 in July 2016.1. Scope*1.1 This specification covers ten types of portland cement, as fo
3、llows (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 is desired.
4、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 II(MH), wh
5、ere 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 resistance
6、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 all types
7、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 values stated i
8、n 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-pound units or
9、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 which provide
10、 explanatory material. These notes and footnotes(excluding those in tables and figures) shall not be considered as requirements of the standard.1.4 This international standard was developed in accordance with internationally recognized principles on standardizationestablished in the Decision on Prin
11、ciples for the Development of International Standards, Guides and Recommendations issuedby the World Trade Organization Technical Barriers to Trade (TBT) Committee.2.

Ingredients5.1 The cement covered by this specification shall contain no ingredients except as follows:5.1.1 Portland cement clinker.5.1.2 Water or calcium sulfate, or both. The amounts shall be such that the limits s
30、hown 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 thisstandard are met (see Note 3). The limestone, defined in Terminology C51, shall be naturally occurring and
31、 consist of at least 70 %by mass of one or more of the mineral forms of calcium carbonate. If limestone is used, the manufacturer shall report the amountused, expressed as a percentage of cement mass, as determined using AnnexA2, along with the oxide composition of the limestone.NOTE 3The standard p
32、ermits up to 5 % by mass of the final cement product to be naturally occurring, finely ground This standard permits portlandcement to contain limestone, but does not require that limestone be added to an ingredient in the cement.

33、er.5.1.4 Inorganic processing additions. The amount shall be not more than 5.0 % by mass of cement. Not more than one inorganicprocessing addition shall be used at a time. For amounts greater than 1.0 %, they shall have been shown to meet the requirementsof Specification C465 for the inorganic proce
34、ssing addition in the amount used or greater. If an inorganic processing addition isused, the manufacturer shall report the amount used, expressed as a percentage of cement mass, along with the oxide compositionof the processing addition. See Note 4.NOTE 4These requirements are based on data and rec
35、ommendations by Taylor.35.1.5 Organic Processing additions. They shall have been shown to meet the requirements of Specification C465 in the amountsused or greater and the total amount of organic processing additions used shall not exceed 1.0 % by mass of cement.5.1.6 Air-entraining addition (for ai
36、r-entraining portland cement only). 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 conform to the respective standard chemical requirementsprescribed in Table 1. In addition,
37、 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 seven-day heat of hydration limit of 335 kJ/kg 80 cal/g, or a Test Method C1702 three-day heat o
38、f hydration limit of 315 kJ/kg 75 cal g.NOTE 6There are cases where performance of a cement is improved with SO3 in excess of the Table 1 limits in this specification. Test Method GuideC563 is one of several methods a manufacturer can use to evaluate the effect of sulfate content on cement character
39、istics. Whenever SO3 content of acement exceeds 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 stan
40、dard physical requirementsprescribed in Table 3. In addition, optional physical requirements are shown in Table 4.3 Taylor, P., “Specifications and Protocols for Acceptance Tests on Processing Additions in Cement Manufacturing,” NCHRP Report 607, Transportation Research Board,Washington, DC 20008, 9
