Designation:C1810/C1810M19Standard Guide forComparing Performance of Concrete-Making MaterialsUsing Mortar Mixtures1This standard is issued under the fixed designation C1810/C1810M;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.Scope1.1 This guide provides information on how to compare therelative performance and potential incompatibility of combi-nations of concrete-making materials.Performance tests onfresh and early-age properties of mortar mixtures can be usefulindicators of concrete performance using similar materials.Theperformance tests described in this guide include mortar-slump,mortar spread,mortar-workability retention,time ofsetting,air entrainment,and hydration kinetics.1.2 UnitsThe values stated in either SI units or inch-pound units are to be regarded separately as standard.Thevalues stated in each system may not be exact equivalents;therefore,each system shall be used independently of the other.Combining values from the two systems may result in non-conformance with this guide.Some values only have SI unitsbecause the inch-pound equivalents are not used in guide.1.3 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,health,and environmental practices and deter-mine the applicability of regulatory limitations prior to use.WarningFresh hydraulic cementitious mixtures are causticand may cause burns to skin and tissue upon prolongedexposure.21.4 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:3C70 Test Method for Surface Moisture in Fine AggregateC125 Terminology Relating to Concrete and Concrete Ag-gregatesC128 Test Method for Relative Density(Specific Gravity)and Absorption of Fine AggregateC185 Test Method for Air Content of Hydraulic CementMortarC305 Practice for Mechanical Mixing of Hydraulic CementPastes and Mortars of Plastic ConsistencyC403/C403M Test Method for Time of Setting of ConcreteMixtures by Penetration ResistanceC494/C494M Specification for Chemical Admixtures forConcreteC566 Test Method for Total Evaporable Moisture Content ofAggregate by DryingC778 Specification for Standard SandC1679 Practice for Measuring Hydration Kinetics of Hy-draulic Cementitious Mixtures Using Isothermal Calorim-etryE11 Specification for Woven Wire Test Sieve Cloth and TestSievesE2251 Specification for Liquid-in-Glass ASTM Thermom-eters with Low-Hazard Precision LiquidsIEEE/ASTM SI 10 American National Standard for MetricPractice2.2 ISO Standard:4ISO 679 CementTest MethodsDetermination of Strength1This guide is under the jurisdiction of ASTM Committee C09 on Concrete andConcrete Aggregates and is the direct responsibility of Subcommittee C09.48 onPerformance of Cementitious Materials and Admixture Combinations.Current edition approved Feb.1,2019.Published April 2019.DOI:10.1520/C1810_C1810M-19.2Section 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.4Available from International Organization for Standardization(ISO),ISOCentral Secretariat,BIBC II,Chemin de Blandonnet 8,CP 401,1214 Vernier,Geneva,Switzerland,http:/www.iso.org.Copyright 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 3.Terminology3.1 DefinitionsFor definitions of terms used in this guide,refer to Terminology C125.3.2 Definitions of Terms Specific to This Standard:3.2.1 mortar-slumpvertical distance between the originaland displaced position of the center of the top surface of mortarwhen tested with the mortar-slump mold.3.2.2 mortar-spreaddistance of lateral flow of mortarfrom the mortar-slump test.3.2.3 mortar-slump retention timethe duration of timeover which the mortar mixture maintains at least 50%of itsinitial mortar-slump.3.2.4 up-front addition of admixtureconcurrent addition ofadmixture with the mixing water t
