1、Designation: C 33 03Standard Specification forConcrete Aggregates1This standard is issued under the fixed designation C 33; the number immediately following the designation indicates the year of originaladoption or, in the case of revision, the year of last revision. A number in parentheses indicate
2、s the year of last reapproval. A superscriptepsilon (e) 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 fine and coa
3、rse 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 adequate to ensu
4、re 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 concrete s
5、urface. 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 aggregate, the
6、 nominal maximum sizeof the aggregate, and other specific grading requirements.Those responsible for selecting the proportions for the concretemixture shall have the responsibility of determining the pro-portions of fine and coarse aggregate and the addition ofblending aggregate sizes if required or
