Standard Specification for Concrete Aggregates1

1 Designation: C 33 03 Standard Specification forConcrete Aggregates1 This 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 indicates the year of last reapproval. A superscriptepsilon (e) indicates an editorial change since the last revision or Standard has been approved for use by agencies of the Department of Scope* This specification defines the requirements for gradingand quality of fine and coarse aggregate (other than lightweightor heavyweight aggregate)

2 For use in This specification is for use by a contractor, concretesupplier, or other purchaser as part of the purchase documentdescribing the material to be This specification is regarded as adequate 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 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 This specification is also for use in project specificationsto define the quality of aggregate, the nominal maximum sizeof the aggregate.

3 And other specific grading 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 The values stated in SI units are to be regarded as thestandard. The values given in parentheses are for The text of this Standard references notes and footnoteswhich provide explanatory material.
