Designation:C110508a(Reapproved 2016)Standard Test Method forLength Change of Concrete Due to Alkali-Carbonate RockReaction1This standard is issued under the fixed designation C1105;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.1.Scope*1.1 This test method covers the determination,by measure-ment of length change of concrete prisms,the susceptibility ofcement-aggregate combinations to expansive alkali-carbonatereaction involving hydroxide ions associated with alkalies(sodium and potassium)and certain calcitic dolomites anddolomitic limestones.1.2 The values stated in SI units are to be regarded as thestandard.No other units of measurement are included in thisstandard.When combined standards are cited,the selection ofmeasurement system is at the users discretion subject to therequirements of the referenced standard.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 and health practices and determine the applica-bility of regulatory limitations prior to use.2.Referenced Documents2.1 ASTM Standards:2C33 Specification for Concrete AggregatesC125 Terminology Relating to Concrete and Concrete Ag-gregatesC150 Specification for Portland CementC157/C157M Test Method for Length Change of HardenedHydraulic-Cement Mortar and ConcreteC233 Test Method for Air-Entraining Admixtures for Con-creteC294 Descriptive Nomenclature for Constituents of Con-crete AggregatesC295 Guide for Petrographic Examination ofAggregates forConcreteC490 Practice for Use ofApparatus for the Determination ofLength Change of Hardened Cement Paste,Mortar,andConcreteC511 Specification for Mixing Rooms,Moist Cabinets,Moist Rooms,and Water Storage Tanks Used in theTesting of Hydraulic Cements and ConcretesC586 Test Method for PotentialAlkali Reactivity of Carbon-ate Rocks as Concrete Aggregates(Rock-CylinderMethod)C595 Specification for Blended Hydraulic CementsC670 Practice for Preparing Precision and Bias Statementsfor Test Methods for Construction MaterialsC702 Practice for Reducing Samples ofAggregate to TestingSizeD75 Practice for Sampling Aggregates3.Terminology3.1 Terminology used in this standard is defined in Termi-nology C125 or Descriptive Nomenclature C294.4.Significance and Use4.1 Two types of alkali reactivity of aggregates have beendescribed in the literature:the alkali-silica reaction involvingcertain siliceous rocks,minerals,and artificial glasses(1),3andthe alkali-carbonate reaction involving dolomite in certaincalcitic dolomites and dolomitic limestones(2).This testmethod is not recommended as a means to detect combinationssusceptible to expansion due to alkali-silica reaction since itwas not evaluated for this use in the work reported by Buck(2).This test method is not applicable to aggregates that do notcontain or consist of carbonate rock(see Descriptive Nomen-clature C294).4.2 This test method is intended for evaluating the behaviorof specific combinations of concrete-making materials to beused in the work.However,provisions are made for the use ofsubstitute materials when required.This test method assessesthe potential for expansion of concrete caused by alkali-carbonate rock reaction from tests performed under prescribedlaboratory curing conditions that will probably differ from field1This test method is under the jurisdiction of ASTM Committee C09 onConcrete and Concrete Aggregatesand is the direct responsibility of SubcommitteeC09.26 on Chemical Reactions.Current edition approved Dec.1,2016.Published December 2016.Originallyapproved in 1989.Last previous edition approved in 2008 as C1105 08a.DOI:10.1520/C1105-08AR16.2For 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.3The boldface numbers in parentheses refer to the list of references at the end ofthis test method.*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 conditions.Thus,actual field performance will not be dupli-cated due to differences in wetting and drying,temperature,other factors,or combinations of these(see Appendix X1).4.3 Use of this test method is of particular value whensamples of aggregate from a source have been determined tocontain constituents that are regarded as capable of participa-tion in a potentially deleterious alkali-carbonate rock reactioneither by petrographic examination,Guide C295,by the rockcylinder test,Test Method C586,by service record;or by acombination of t
