Designation:C65898(Reapproved 2012)Standard Specification forChemical-Resistant Resin Grouts for Brick or Tile1This standard is issued under the fixed designation C658;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 Department of Defense.1.Scope1.1 This specification covers the requirements for chemical-resistant resin grouts for filling joints of chemical-resistantbrick or tile units.For use of these materials,see PracticeC723.(For mortars,see Specification C395.)1.2 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.NOTE1Resin grouts and mortars are differentiated as follows:Resingrouts are applied to the joints,generally14in.(6 mm)wide,after thebrick or tile are set in place and the setting bed has hardened(grouting ortilesetters method).Resin mortars are trowelled onto the brick or tile insufficient quantity to achieve a18-in.(3-mm)thick joint after the brick ortile are laid in place(buttering or bricklayers method).2.Referenced Documents2.1 ASTM Standards:2C307 Test Method for Tensile Strength of Chemical-Resistant Mortar,Grouts,and Monolithic SurfacingsC308 Test Methods for Working,Initial Setting,and ServiceStrength Setting Times of Chemical-Resistant Resin Mor-tarsC395 Specification for Chemical-Resistant Resin MortarsC413 Test Method for Absorption of Chemical-ResistantMortars,Grouts,Monolithic Surfacings,and PolymerConcretesC531 Test Method for Linear Shrinkage and Coefficient ofThermal Expansion of Chemical-Resistant Mortars,Grouts,Monolithic Surfacings,and Polymer ConcretesC579 Test Methods for Compressive Strength of Chemical-Resistant Mortars,Grouts,Monolithic Surfacings,andPolymer ConcretesC723 Practice for Chemical-Resistant Resin Grouts forBrick or TileC904 Terminology Relating to Chemical-Resistant Nonme-tallic Materials3.Terminology3.1 DefinitionsFor definitions of terms used in thisspecification,see Terminology C904.4.Types of Resins,Fillers,and Setting Agents4.1 The liquid resins may be furan,epoxy,vinyl ester,orothers capable of forming chemical-resistant grout when mixedwith a suitable setting agent and filler.4.2 The fillers may be silica,carbon,or other chemicalresistant materials.Fillers may be supplied as a separatecomponent or can be combined as a premix with the liquidresin and/or setting agent.4.3 The setting agents may include amines,polyamides,peroxides,acids,or other reactants.Setting agents may besupplied as a separate component to be incorporated into theresin and filler at the time of mixing or may be supplied as aconstituent of the filler.5.General Requirements5.1 When these components are mixed at 65 to 85F(18 to29C)they form a uniform and flowable grout.The mixedgrout shall be of a viscosity such that it will readily flow to thefull depth of the open joint.5.2 The filler shall have properly graded particles,notexceeding132in.(1 mm),that will permit the filling of aminimum joint width of316in.(5 mm).5.3 The service limitations of the grout shall be defined bythe manufacturer.6.Physical Requirements6.1 Chemical-resistant resin tile grouts prepared from thesematerials shall conform to the physical requirements prescribedin Table 1.7.Test Methods7.1 Determine the properties enumerated in this specifica-tion in accordance with the following methods:1This specification is under the jurisdiction of ASTM Committee C03 onChemical-Resistant Nonmetallic Materialsand is the direct responsibility of Sub-committee C03.02 on Monolithics,Grouts and Polymer Concretes.Current edition approved Aug.1,2012.Published September 2012.Originallyapproved in 1970.Last previous edition approved in 2008 as C658 98(2008).DOI:10.1520/C0658-98R12.2For 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.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 7.1.1 Setting Time Test Method C308.7.1.2 Compressive StrengthTest Method C579.7.1.3 Tensile Strength Test Method C307.7.1.4 Water Absorption Test Method C413.7.1.5 Linear Shrinkage Test Method C531.8.Rejection8.1 The grout may be rejected if it fails to meet any of therequirements of this specification.9.Packaging and Package Marking9.1 Each component shall be packaged to prevent deterio-ration in storage and shall be labeled in such a manner toindicate clearly the other components with which it is to beused.9.2 The supplier,at his discretion and responsibility,mayi
