Designation:C12516Standard Terminology Relating toConcrete and Concrete Aggregates1This standard is issued under the fixed designation C125;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.This standard has been approved for use by agencies of the U.S.Department of Defense.1.Scope*1.1 This standard is a compilation of definitions of terms asthey are used in standards under the jurisdiction of CommitteeC09.1.2 Other terminology under the jurisdiction of CommitteeC09 is included in two specialized standards.Terms relating toconstituents of concrete aggregates are defined in DescriptiveNomenclature C294.Terms relating to constituents of aggre-gates for radiation-shielding concrete are defined in Descrip-tive Nomenclature C638.1.3 Related terminology for hydraulic cement is included inTerminology C219.Additionally,the American Concrete Insti-tute(ACI)has a standard terminology for the concrete indus-try.2In the event of conflict between definitions in TerminologyC125 and definitions in the ACI standard terminology or inTerminology C219,definitions in Terminology C125 shallgovern for Committee C09 standards.1.4 When a term is used in an ASTM standard for whichCommittee C09 is responsible,it is included herein only if usedin more than one Committee C09 standard.NOTE1The subcommittee responsible for this standard will reviewdefinitions on a five-year basis to determine if the definition is stillappropriate as stated.Revisions will be made when determined necessary.The year shown in parentheses at the end of a definition indicates the yearthe definition or revision to the definition was approved.A letter R and ayear indicate when the definition was reviewed.No date indicates the termhas not yet been reviewed.2.Referenced Documents2.1 ASTM Standards:3C94/C94M Specification for Ready-Mixed ConcreteC143/C143M Test Method for Slump of Hydraulic-CementConcreteC219 Terminology Relating to Hydraulic CementC294 Descriptive Nomenclature for Constituents of Con-crete AggregatesC403/C403M Test Method for Time of Setting of ConcreteMixtures by Penetration ResistanceC494/C494M Specification for Chemical Admixtures forConcreteC511 Specification for Mixing Rooms,Moist Cabinets,Moist Rooms,and Water Storage Tanks Used in theTesting of Hydraulic Cements and ConcretesC638 Descriptive Nomenclature of Constituents of Aggre-gates for Radiation-Shielding ConcreteC939 Test Method for Flow of Grout for Preplaced-Aggregate Concrete(Flow Cone Method)C1074 Practice for Estimating Concrete Strength by theMaturity MethodC1077 Practice for Agencies Testing Concrete and ConcreteAggregates for Use in Construction and Criteria forTesting Agency EvaluationC1240 Specification for Silica Fume Used in CementitiousMixturesC1437 Test Method for Flow of Hydraulic Cement MortarC1610/C1610M Test Method for Static Segregation of Self-Consolidating Concrete Using Column TechniqueC1611/C1611M Test Method for Slump Flow of Self-Consolidating ConcreteE135 Terminology Relating to Analytical Chemistry forMetals,Ores,and Related Materials3.Terms and Their Definitionsabsorption,nthe process by which a liquid is drawn into andtends to fill permeable pores in a porous solid body;also,theincrease in mass of a porous solid body resulting from thepenetration of a liquid into its permeable pores.(R2008)DISCUSSIONIn the case of concrete and concrete aggregates,unlessotherwise stated,the liquid involved is water,the increase in mass isthat which does not include water adhering to the outside surface,theincrease in mass is expressed as a percentage of the dry mass of thebody and the body is considered to be“dry”when it has been treatedby an appropriate process to remove uncombined water,such as dryingto constant mass at a temperature between 100 and 110C.1This terminology is under the jurisdiction of ASTM Committee C09 onConcrete and Concrete Aggregates and is the direct responsibility of SubcommitteeC09.91 on Terminology.Current edition approved Dec.15,2016.Published January 2017.Originallyapproved in 1936.Last previous edition approved in 2015 as C12515b.DOI:10.1520/C0125-16.2Available from American Concrete Institute(ACI),P.O.Box 9094,FarmingtonHills,MI 48333-9094,http:/www.terminology.concrete.org.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
