Designation:C928/C928M13Standard Specification forPackaged,Dry,Rapid-Hardening Cementitious Materials forConcrete Repairs1This standard is issued under the fixed designation C928/C928M;the number immediately following the designation indicates the yearof original adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.A superscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope*1.1 This specification covers packaged,dry,cementitiousmortar or concrete materials for rapid repairs to hardenedhydraulic-cement concrete pavements and structures.Materialsthat contain organic compounds,such as bitumens,epoxyresins,and polymers,as the principal binder are not included.1.1.1 Packaged,dry,concrete material contains aggregate ofwhich at least 5%by mass of the total mixture is retained ona 9.5-mm 38-in.sieve.1.1.2 Packaged,dry,mortar material contains aggregate ofwhich less than 5%by mass of the total mixture is retained ona 9.5-mm 38-in.sieve.1.2 Aqueous solutions,aqueous emulsions or dispersionsmay be included as components of the packaged materials.Themanufacturer may specify that these liquids are to replace someor all of the mixing water.1.3 Aggregates must be included as a component of thepackaged materials.The manufacturer may recommend jobsite addition of specific amounts and types of additionalaggregates to his product for some uses.However,suchreformulated products are not within the scope of this specifi-cation.1.4 The values stated in either SI units or inch-pound unitsare to be regarded separately as standard.The values stated ineach system may not be exact equivalents;therefore,eachsystem shall be used independently of the other.Combiningvalues from the two systems may result in non-conformancewith the standard.1.5 The following safety hazards caveat pertains to the testmethods portion of this specification:This standard does notpurport to address all of the safety concerns,if any,associatedwith its use.It is the responsibility of the user of this standardto establish appropriate safety and health practices anddetermine the applicability of regulatory limitations prior touse.2.Referenced Documents2.1 ASTM Standards:2C39/C39M Test Method for Compressive Strength of Cylin-drical Concrete SpecimensC78 Test Method for Flexural Strength of Concrete(UsingSimple Beam with Third-Point Loading)C109/C109M Test Method for Compressive Strength ofHydraulic Cement Mortars(Using 2-in.or 50-mm CubeSpecimens)C125 Terminology Relating to Concrete and Concrete Ag-gregatesC143/C143M Test Method for Slump of Hydraulic-CementConcreteC157/C157M Test Method for Length Change of HardenedHydraulic-Cement Mortar and ConcreteC192/C192M Practice for Making and Curing Concrete TestSpecimens in the LaboratoryC403/C403M Test Method for Time of Setting of ConcreteMixtures by Penetration ResistanceC494/C494M Specification for Chemical Admixtures forConcreteC666/C666M Test Method for Resistance of Concrete toRapid Freezing and ThawingC670 Practice for Preparing Precision and Bias Statementsfor Test Methods for Construction MaterialsC672/C672M Test Method for Scaling Resistance of Con-crete Surfaces Exposed to Deicing ChemicalsC702 Practice for Reducing Samples ofAggregate to TestingSizeC778 Specification for SandC882 Test Method for Bond Strength of Epoxy-Resin Sys-tems Used With Concrete By Slant ShearC1012 Test Method for Length Change of Hydraulic-Cement Mortars Exposed to a Sulfate SolutionE96/E96M Test Methods for Water Vapor Transmission ofMaterials1This specification is under the jurisdiction of ASTM Committee C09 onConcrete and Concrete Aggregatesand is the direct responsibility of SubcommitteeC09.43 on Packaged Dry Combined Materials.Current edition approved Dec.15,2013.Published January 2014.Originallyapproved in 1980.Last previous edition approved in 2009 as C928/C928M 09.DOI:10.1520/C0928_C0928M-13.2For 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 3.Terminology3.1 DefinitionsFor difinitions of terms used in this speci-fication refer to Terminology C125.4.Materials and Manufacture4.1 Three types of packaged,dry,rapid-hardening concreteand three types of packaged,dry,rapid-hardening mortar areidentified in Table 1.5.Chemical Composition5.1 If the material contains soluble chlorides or otheringredients in sufficient quantity to cause corrosion to steelreinforcement,the package markings shall contain the follow-ing statement in letter size no smaller than the directions foruse:This material is not recommended for use in a moist environment in contactwith steel reinforcement.5.
