2、ear of last revision.A number in parentheses indicates the year of lastreapproval.A superscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 This practice covers procedures for fabricating andtesting specimens in the laboratory and the field using arepresen
3、tative sample of ultra-high performance concrete(UHPC),for the purpose of determining the properties of thematerial.This practice is applicable to UHPC with a specifiedcompressive strength of at least 120 MPa(17 000 psi),withnominal maximum size aggregate of less than 5 mm 14in.and a flow between 20
4、0 and 250 mm 8 and 10 in.as measuredby the modified flow table test described in Section 6.1.2 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 independent
