Asuperscript 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 grading and qua
3、lity of fine and coarse aggregate (other than lightweight orheavyweight aggregate) for use in concrete.21.2 This specification is for use by a contractor, concrete supplier, or other purchaser as part of the purchase documentdescribing the material to be furnished.NOTE 1This specification is regarde
4、d as adequate to ensure satisfactory materials for most concrete. It is recognized that, for certain work or in certainregions, it may be either more or less restrictive than needed. For example, where aesthetics are important, more restrictive limits may be consideredregarding impurities that would
5、 stain the concrete surface. The specifier should ascertain that aggregates specified are or can be made available in thearea of the work, with regard to grading, physical, or chemical properties, or combination thereof.1.3 This specification is also for use in project specifications to define the q
6、uality of aggregate, the nominal maximum size ofthe aggregate, and other specific grading requirements. Those responsible for selecting the proportions for the concrete mixtureshall have the responsibility of determining the proportions of fine and coarse aggregate and the addition of blending aggre

The values stated in eachsystem may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from thetwo system
