2、ses indicates the year of last reapproval.A superscript epsilon () indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the Department of Defense.1. Scope*1.1 This specification defines the requirements for gradingand quality of f

3、ine and coarse aggregate (other than lightweightor heavyweight aggregate) for use in concrete.21.2 This specification is for use by a contractor, concretesupplier, or other purchaser as part of the purchase documentdescribing the material to be furnished.NOTE 1This specification is regarded as adequ

4、ate to ensure satisfac-tory materials for most concrete. It is recognized that, for certain work orin certain regions, it may be either more or less restrictive than needed. Forexample, where aesthetics are important, more restrictive limits may beconsidered regarding impurities that would stain the

5、 concrete surface. Thespecifier should ascertain that aggregates specified are or can be madeavailable in the area of the work, with regard to grading, physical, orchemical properties, or combination thereof.1.3 This specification is also for use in project specificationsto define the quality of agg

7、required or approved.1.4 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 in
