1、Designation: C150/C150M 15C150/C150M 16Standard 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.2.

28、, three-day heat of hydration testing by Test Method C1702 shall be conducted at least once every six months. Such testing shall not be used for acceptanceor rejection of the cement, but results shall be reported for informational purposes.C150/C150M 1625.1.2 Water or calcium sulfate, or both. The a

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
30、 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 shall report the amountused, expressed as a percentage of cement mass, as determined using AnnexA2, along with the oxide composition
31、 of the limestone.NOTE 3The standard permits up to 5 % by mass of the final cement product to be naturally occurring, 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.5.1.4 Inorganic processi
32、ng 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 processing addition in the amoun
33、t used or greater. If an inorganic processing addition isused, the manufacturer shall report the amount (or range) used, expressed as a percentage of cement mass, along with the oxidecomposition of the processing addition. See Note 4.NOTE 4These requirements are based on data and recommendations by
34、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 air-entraining por
35、tland 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, optional chemic
36、al 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 of hydration limi
37、t 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 C563is one of several methods a manufacturer can use to evaluate the effect of sulfate content on cement characteristics. Whenever SO3 c
38、ontent 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 standard physical requirem
