Designation:C1600/C1600M17Standard Specification forRapid Hardening Hydraulic Cement1This standard is issued under the fixed designation C1600/C1600M;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 specification is for rapid hardening hydraulic ce-ments.This is a specification giving performance requirements.There are no restrictions on the composition of the cement orits constituents.1.2 The specification classifies cements by type based onspecific requirements for very early compressive strengthdevelopment.1.3 The values stated in either SI units or inch-pound unitsshall be regarded separately as standard.The values stated ineach system are not exact equivalents;therefore,each systemshall be used independently of the other.Combining valuesfrom the two systems may result in nonconformance with thestandard.1.4 The text of this standard refers to notes and footnotesthat provide explanatory material.These notes and footnotes(excluding those in tables and figures)are not requirements ofthe standard.1.5 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.(Warning Freshhydraulic cementitious mixtures are caustic and may causechemical burns to skin and tissue upon prolonged exposure.2)1.6 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:3C109/C109M Test Method for Compressive Strength ofHydraulic Cement Mortars(Using 2-in.or 50-mm CubeSpecimens)C114 Test Methods for Chemical Analysis of HydraulicCementC151 Test Method for Autoclave Expansion of HydraulicCementC183 Practice for Sampling and the Amount of Testing ofHydraulic CementC186 Test Method for Heat of Hydration of HydraulicCementC191 Test Methods for Time of Setting of Hydraulic Cementby Vicat NeedleC219 Terminology Relating to Hydraulic CementC441 Test Method for Effectiveness of Pozzolans or GroundBlast-Furnace Slag in Preventing Excessive Expansion ofConcrete Due to the Alkali-Silica ReactionC596 Test Method for Drying Shrinkage of Mortar Contain-ing Hydraulic CementC1012 Test Method for Length Change of Hydraulic-Cement Mortars Exposed to a Sulfate SolutionC1038 Test Method for Expansion of Hydraulic CementMortar Bars Stored in WaterC1437 Test Method for Flow of Hydraulic Cement Mortar3.Terminology3.1 Definitions:3.1.1 For definitions of terms used in this specification,seeTerminology C219.3.2 Definitions of Terms Specific to This Standard:3.2.1 Rapid Hardening Hydraulic Cement,na hydraulicor blended hydraulic cement which exhibits rapid strength gain1This test method is under the jurisdiction of ASTM Committee C01 on Cementand is the direct responsibility of Subcommittee C01.13 on Special Cements.Current edition approved May 1,2017.Published May 2017.Originallyapproved in 2007.Last previous edition approved in 2011 as C1600/C1600M 11.DOI:10.1520/C1600_C1600M-17.2See the section on Safety,Manual of Cement Testing,Annual Book of ASTMStandards,Vol 04.01.3For 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 during the first 24 h of hydration,with or without otherconstituents,processing additions,and functional additions.4.Nomenclature,Classifications and Use4.1 Cements conforming to this specification shall be des-ignated“Rapid Hardening Hydraulic Cement”with the highearly strength gain characteristic indicated by type in accor-dance with the types described in section 4.2.When the type isnot specified,the requirement of Type GRH shall apply.4.2 The specification is for four types of rapid hardeningcement as follows:4.2.1 Type URHUltra Rapid Hardening For use whereultra high early strength is desired(see Table 1).4.2.2
