1、Designation:C10/C10M14Standard Specification forNatural Cement1This standard is issued under the fixed designation C10/C10M;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of last revision.A number in parentheses indicates t
2、he year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope*1.1 This specification covers natural cement and quick-setting natural cement.NOTE1Examples of typical past uses of natural cement include unitmasonry mortar,cement plaster,gr
3、out,whitewash,and concrete.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 systems may result
4、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.Values are stated
5、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.2.Referenced Documents2
