Designation:C1610/C1610M17Standard Test Method forStatic Segregation of Self-Consolidating Concrete UsingColumn Technique1This standard is issued under the fixed designation C1610/C1610M;the number immediately following the designation indicates theyear of original adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of lastreapproval.A superscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope*1.1 This test method covers the determination of staticsegregation of self-consolidating concrete(SCC)by measuringthe coarse aggregate content in the top and bottom portions ofa cylindrical specimen(or column).1.2 This test method is not applicable to self-consolidatingconcrete containing lightweight aggregate.1.3 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.1.4 The text of this standard references notes and footnotesthat provide explanatory material.These notes and footnotes(excluding those in tables and figures)shall not be consideredas requirements of the standard.1.5 This test method is applicable under laboratory and fieldconditions.1.6 This standard does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.(WarningFreshhydraulic cementitious mixtures are caustic and may causechemical burns to skin and tissue upon prolonged exposure.2)1.7 This international standard was developed in accor-dance with internationally recognized principles on standard-ization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recom-mendations issued by the World Trade Organization TechnicalBarriers to Trade(TBT)Committee.2.Referenced Documents2.1 ASTM Standards:3C125 Terminology Relating to Concrete and Concrete Ag-gregatesC127 Test Method for Relative Density(Specific Gravity)and Absorption of Coarse AggregateC173/C173M Test Method forAir Content of Freshly MixedConcrete by the Volumetric MethodC192/C192M Practice for Making and Curing Concrete TestSpecimens in the LaboratoryC231 Test Method for Air Content of Freshly Mixed Con-crete by the Pressure MethodC1712 Test Method for Rapid Assessment of Static Segre-gation Resistance of Self-Consolidating Concrete UsingPenetration TestC1758/C1758M Practice for Fabricating Test Specimenswith Self-Consolidating ConcreteD1785 Specification for Poly(Vinyl Chloride)(PVC)PlasticPipe,Schedules 40,80,and 1203.Terminology3.1 Definitions:3.1.1 For definitions of terms used in this test method,referto Terminology C125.3.2 Definitions of Terms Specific to This Standard:3.2.1 static segregation,nsettlement of coarse aggregateparticles in an undisturbed mass of fresh concrete.4.Summary of Test Method4.1 Asample of freshly-mixed self-consolidating concrete isplaced in a cylindrical mold without tamping or vibration.Themold is separated into three sections representing differentlevels of the cylindrical specimen(or column).Portions ofSCC from the top and bottom section are washed on a 4.75 mm(No.4)sieve,leaving the coarse aggregate on the sieve.Themasses of coarse aggregate in the top and the bottom sectionsare determined and the percent static segregation is calculated.1This test method is under the jurisdiction of ASTM Committee C09 onConcrete and Concrete Aggregates and is the direct responsibility of SubcommitteeC09.47 on Self-Consolidating Concrete.Current edition approved June 15,2017.Published July 2017.Originallyapproved in 2006.Last previous edition approved in 2014 as C1610/C1610M 14.DOI:10.1520/C1610_C1610M-17.2Section on Safety Precautions,Manual of Aggregate and Concrete Testing,Annual Book of ASTM Standards,Vol 04.02.3For 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.*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 StatesThis international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade(TBT)Committee.1 5.Significance and Use5.1 This test method provides users with a procedure todetermine the potential static segregation of self-consolidatingconcrete.NOTE1This test method ma
