Designation:C33/C33M161Standard 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 indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1NOTEEditorially corrected 3.2.1 and Footnote B of Table 1 in November 2016.1.Scope*1.1 This specification defines the requirements for gradingand quality of fine 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.NOTE1This 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 thereof.1.3 This specification is also for use in project specificationsto define the quality of aggregate,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 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 non-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 Test Method for Bulk Density(“Unit Weight”)and Voids in AggregateC40 Test Method for Organic Impurities in Fine Aggregatesfor ConcreteC87 Test Method for Effect of Organic Impurities in FineAggregate on Strength of MortarC88 Test Method for Soundness of Aggregates by Use ofSodium Sulfate or Magnesium SulfateC117 Test Method for Materials Finer than 75-m(No.200)Sieve in Mineral Aggregates by WashingC123 Test Method for Lightweight Particles in AggregateC125 Terminology Relating to Concrete and Concrete Ag-gregatesC131 Test Method for Resistance to Degradation of Small-Size Coarse Aggregate by Abrasion and Impact in the LosAngeles MachineC136 Test Method for Sieve Analysis of Fine and CoarseAggregatesC142 Test Method for Clay Lumps and Friable Particles inAggregatesC150 Specification for Portland CementC227 Test Method for Potential Alkali Reactivity ofCement-Aggregate Combinations(Mortar-Bar Method)C289 Test Method for Potential Alkali-Silica Reactivity ofAggregates(Chemical Method)(Withdrawn 2016)4C294 Descriptive Nomenclature for Constituents of Con-crete AggregatesC295 Guide for Petrographic Examination ofAggregates forConcreteC311 Test Methods for Sampling and Testing Fly Ash orNatural Pozzolans for Use in Portland-Cement ConcreteC330 Specification for Lightweight Aggregates for Struc-tural Concrete1This specification is under the jurisdiction of ASTM Committee C09 onConcrete and Concrete Aggregates and is the direct responsibility of SubcommitteeC09.20 on Normal Weight Aggregates.Current edition approved Feb.1,2016.Published March 2016.Originallyapproved in 1921.Last previous edition approved in 2013 as C33/C33M 13.DOI:10.1520/C0033_C0033M-16.2For lightweight aggregates,see Specifications C330,C331,and C332;forheavyweight aggregates see Specification C637 and Descriptive NomenclatureC638.3For referenced ASTM standards,visit the ASTM website,www.astm.org,orcontact ASTM Customer Service at serviceastm.org.For Annual Book of ASTMStandards volume information,refer to the standards Document Summary page onthe ASTM website.4The last approved version of this historical standard is referenced onwww.astm.org.*A Summary of Changes section appears at the end of this standardCopyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 C331 Specification for Lightweight Aggregates for ConcreteMasonry UnitsC332 Specification for Lightweight Aggregates for Insulat-ing ConcreteC342 Test Method for Potential Volume Change of Cement-Aggregate Combinations(Withdrawn 2001)4C441 Test Method for Effectiveness of Pozzolans or GroundBlast-Furnace Slag in Preventing
