1、Designation:C150/C150M17Standard 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 indica
2、tes 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 are not req
3、uired.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.1.1.5 Type I
4、I(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 IIIAAir-entrain
5、ing 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.NOTE1Some cements are designated with a combined typeclassification,such as Type I/II,indicating that the ce
6、ment meets therequirements of the indicated types and is being offered as suitable for usewhen either type is desired.NOTE2Cement 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,determine whether the propo
7、sed 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.Combiningvalues from the two
8、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 measurementsmade in other units or SI units
9、.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 requirements of the standard.1.4
