1、Designation: C33/C33M 11Standard Specification forConcrete Aggregates1This standard is issued under the fixed designation C33/C33M; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision. A number in parentheses
2、indicates the year of last reapproval. 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 gradingand quality of fine
3、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 adequate
4、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 con
5、crete 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 aggrega
6、te, the 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 requ
7、ired 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 non
8、-conformancewith the standard.1.5 The text of this standard references notes and footnoteswhich provide explanatory material. These notes and footnotes(excluding those in tables and figures) shall not be consideredas requirements of this standard.2. Referenced Documents2.1 ASTM Standards:3C29/C29M T
