1、Designation: C150/C150M 15Standard 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 parentheses
2、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 specifiedfor any other type a
3、re not required.1.1.2 Type IAAir-entraining cement for the same uses asType I, where air-entrainment is desired.1.1.3 Type IIFor general use, more especially when mod-erate sulfate resistance is desired.1.1.4 Type IIAAir-entraining cement for the same uses asType II, where air-entrainment is desired
4、.1.1.5 Type II(MH)For general use, more especially whenmoderate heat of hydration and moderate sulfate resistance aredesired.1.1.6 Type II(MH)AAir-entraining cement for the sameuses as Type II(MH), where air-entrainment is desired.1.1.7 Type IIIFor use when high early strength is desired.1.1.8 Type
5、IIIAAir-entraining cement for the same use asType III, where air-entrainment is desired.1.1.9 Type IVFor use when a low heat of hydration isdesired.1.1.10 Type VFor use when high sulfate resistance isdesired.NOTE 1Some cements are designated with a combined typeclassification, such as Type I/II, ind
6、icating that the cement meets therequirements of the indicated types and is being offered as suitable for usewhen either type is desired.NOTE 2Cement conforming to the requirements for all types are notcarried in stock in some areas. In advance of specifying the use of cementother than Type I, deter
7、mine whether the proposed type of cement is, orcan be made, available.1.2 The values stated in either SI units or inch-pound unitsare to be regarded separately as standard. The values stated ineach system may not be exact equivalents; therefore, eachsystem shall be used independently of the other. C
8、ombiningvalues from the two systems may result in non-conformancewith the standard. Values in SI units or inch-pound units shallbe obtained by measurement in SI units or inch-pound unitsor by appropriate conversion, using the Rules for Conversionand Rounding given in IEEE/ASTM SI 10, of measurements
9、made in other units or SI units. Values are stated in only SIunits when inch-pound units are not used in practice.1.3 The text of this standard references notes and footnoteswhich provide explanatory material. These notes and footnotes(excluding those in tables and figures) shall not be consideredas

The amounts shallbe such that the limits shown in Table 1 for sulfur trioxide andloss-on-ignition are not exceeded.5.1.3 Limestone.
21、The amount shall not be more than 5.0 %by mass such that the chemical and physical requirements ofthis standard are met (see Note 3). The limestone, defined inTerminology C51, shall be naturally occurring and consist of atleast 70 % by mass of one or more of the mineral forms ofcalcium carbonate.NOT
22、E 3The standard permits up to 5 % by mass of the final cementproduct to be naturally occurring, finely ground limestone, but does notrequire that limestone be added to the cement. Cement without groundlimestone can be specified in the contract or order.5.1.4 Inorganic processing additions. The amoun

32、 Chemical Composition6.1 Portland cement of each of the ten types shown inSection 1 shall conform to the respective standard chemicalrequirements prescribed in Table 1. In addition, optionalchemical requirements are shown in Table 2.NOTE 5The limit on the sum, C3S + 4.75C3A, in Table 1 providescontr

34、 the Table 1 limits in this specification. Test MethodC563 is one of several methods a manufacturer can use to evaluate theeffect of sulfate content on cement characteristics. Whenever SO3contentof a cement exceeds Table 1 limits, Test Method C1038 results provideevidence that excessive expansion do
