Designation:C47616Standard Specification forGrout for Masonry1This standard is issued under the fixed designation C476;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 specification covers two types of grout,fine andcoarse grout,for use in the construction of masonry structures.Each type(fine and coarse)is further classified as conventionalgrout(requiring mechanical consolidation by puddling orvibration when placed)and self-consolidating grout(not re-quiring mechanical consolidation when placed).Conventionalgrout is specified by(1)proportions or(2)strength require-ments.Self-consolidating grout is specified by strength re-quirements.1.2 The text of this specification references notes andfootnotes that provide explanatory material.These notes andfootnotes(excluding those in tables and figures)shall not beconsidered as requirements of this specification.1.3 The values stated in inch-pound units are to be regardedas standard.The values given in parentheses are mathematicalconversions to SI units that are provided for information onlyand are not considered standard.2.Referenced Documents2.1 ASTM Standards:2C5 Specification for Quicklime for Structural PurposesC143/C143M Test Method for Slump of Hydraulic-CementConcreteC150/C150M Specification for Portland CementC207 Specification for Hydrated Lime for Masonry Pur-posesC260/C260M Specification for Air-Entraining Admixturesfor ConcreteC404 Specification for Aggregates for Masonry GroutC494/C494M Specification for Chemical Admixtures forConcreteC595/C595M Specification for Blended Hydraulic CementsC618 Specification for Coal Fly Ash and Raw or CalcinedNatural Pozzolan for Use in ConcreteC989/C989M Specification for Slag Cement for Use inConcrete and MortarsC1019 Test Method for Sampling and Testing GroutC1157/C1157M Performance Specification for HydraulicCementC1611/C1611M Test Method for Slump Flow of Self-Consolidating Concrete3.Materials3.1 Materials used as ingredients in grout shall conform tothe requirements specified in 3.1.1 3.1.8.3.1.1 Cementitious MaterialsCementitious materials shallconform to one of the following specifications:3.1.1.1 Portland CementType I,IA,II,IIA,III,and IIIAof Specification C150/C150M.3.1.1.2 Blended CementsType IS,IS(MS),IS-A,IS-A(MS),IP,or IP-Aof Specification C595/C595M or types GU,HE,MS,or HS of Specification C1157/C1157M.3.1.1.3 QuicklimeSpecification C5.3.1.1.4 Hydrated LimeType S of Specification C207.3.1.1.5 Coal Fly Ash or Raw Calcined Natural PozzolanSpecification C618.Addition rates shall be in an amountgoverned by the portland-pozzolan cement category of Speci-fication C595/C595M.The grout produced with blends ofportland cement and fly ash or raw calcined natural pozzolanshall have the compressive strength specified(4.2.1.2 or4.2.2.1).3.1.1.6 Granulated Blast Furnace SlagSpecificationC989/C989M.Addition rates shall be as governed by theportland blast furnace slag cement category of SpecificationC595/C595M.Grouts produced with blends of portland cementand granulated blast furnace slag shall have the compressivestrength specified(4.2.1.2 or 4.2.2.1).3.1.2 Air-Entraining AdmixturesAir-entraining admix-tures shall conform to Specification C260/C260M.3.1.3 AggregatesAggregates shall conform to Specifica-tion C404.3.1.4 WaterWater shall be clean and potable.3.1.5 AdmixturesIntegral waterproofing compounds,accelerators,or other admixtures not mentioned definitely in1This specification is under the jurisdiction of ASTM Committee C12 onMortars and Grouts for Unit Masonryand is the direct responsibility of Subcom-mittee C12.05 on Grout&Grout Admixtures for Masonry.Current edition approved July 15,2016.Published July 2016.Originallyapproved in 1961.Last previous edition approved in 2010 as C476 10.DOI:10.1520/C0476-16.2For 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 States1 the specification shall not be used in grout for use in reinforcedmasonry without approval from the purchaser.3.1.5.1 Admixtures for Ready-Mixed Grout Transported tothe Job SiteRetarding admixtures conforming to Specifica-tion C494/C494M,Type B or D,for producing ready-mixedgrout transported to the job site and meeting 4.2.1.2 arepermitted.3.1.5.2 Admixtures for Self-consolidating GroutHigh-range water-reducing admixtures conforming to SpecificationC494/C494M,Type F or G,and
