1、Designation: C150/C150M 17C150/C150M 18Standard Specification forPortland Cement1This standard is issued under the fixed designation C150/C150M; the number immediately following the designation indicates the yearof original adoption or, in the case of revision, the year of last revision. A number in
2、 parentheses indicates the year of last reapproval.A superscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope*1.1 This specification covers ten types of portland cement, as follows (see Note 2):1.1.1 Type IFor use when the special properties specified for a
3、ny 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.1.1.4 Type IIAAir-entraining cement for the same uses as Type II, where air-entrai
4、nment 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), where air-entrainment is desired.1.1.7 Type IIIFor use when high early strength is d
5、esired.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 is desired.NOTE 1Some cements are designated with a combined type classification,
6、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 are not carried in stock in some areas. In advance of specifying the use of cement
7、 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 in eachsystem may not be exact equivalents; therefore, each system shall be used in
8、dependently 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 by appropriate conversion, using the Rules for Conversion and Rounding givenin IEE
9、E/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 explanatory material. These notes and footnotes(excluding those in tables and fig
10、ures) 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 Principles for the Development of International Standards, Guides and Recommendations

Ordering Information4.1 Orders for material under this specification shall include the following:4.1.1 This
22、 specification number and date,4.1.2 Type or types allowable. If no type is specified,Type I shall be supplied,4.1.3 Any optional chemical requirements from Table 2, if desired, and4.1.4 Any optional physical requirements from Table 4, if desired.5. Ingredients5.1 The cement covered by this specific
23、ation 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 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
24、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 consist of at least 70 %by mass of one or more of the mineral forms of calcium carbonate. If limestone is used, the manufacturer sha
25、ll report the amountused, expressed as a percentage of cement mass, as determined using AnnexA2, along with the oxide composition of the limestone.NOTE 3This standard permits portland cement to contain limestone, but does not require that limestone be an ingredient in the cement. Cementwithout groun
26、d limestone can be specified in the contract or order.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 requir
27、ementsof Specification C465 for the inorganic processing 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
28、.NOTE 4These requirements are based on data and recommendations by Taylor.35.1.5 Organic Processing additions.

32、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. Guide C563 isone of several methods a manufacturer can use to evaluate the effect of sulfate content on cement characteristics. Whenever SO3 content o
33、f 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 standard physical requirementspres
34、cribed in Table 3. In addition, optional physical requirements are shown in Table 4.8.
