Designation:C132415Standard Test Method forExamination and Analysis of Hardened Masonry Mortar1This standard is issued under the fixed designation C1324;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 procedures for petrographicexamination and chemical analysis of samples of masonrymortars.Based upon such examination and analysis,propor-tions of components in masonry mortars can be determined.NOTE1This method is also applicable to hydraulic cement-basedstucco and plaster.Some historic mortars may contain non-resolvableconstituents that may interfere.However,significant information may beobtained by petrographic examinations.1.2 Interpretations and calculations of chemical results aredependent upon results of the petrographic examination.Theuse of the chemical results alone is contrary to the requirementsof this test method.1.3 Procedures for sampling,petrographic examination,chemical analysis,and calculations of component proportionsare given in the following sections:SectionSampling7Petrographic examination8Chemical analysis9Mortar proportion calculations10Report111.4 The values stated in SI units are to be regarded asstandard.No other units of measurement are included in thisstandard.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.2.Referenced Documents2.1 ASTM Standards:2C114 Test Methods for Chemical Analysis of HydraulicCementC125 Terminology Relating to Concrete and Concrete Ag-gregatesC144 Specification for Aggregate for Masonry MortarC270 Specification for Mortar for Unit MasonryC295 Guide for Petrographic Examination ofAggregates forConcreteC457 Test Method for Microscopical Determination of Pa-rameters of the Air-Void System in Hardened ConcreteC823 Practice for Examination and Sampling of HardenedConcrete in ConstructionsC856 Practice for Petrographic Examination of HardenedConcreteC1084 Test Method for Portland-Cement Content of Hard-ened Hydraulic-Cement ConcreteC1180 Terminology of Mortar and Grout for Unit MasonryD1193 Specification for Reagent Water3.Terminology3.1 Terms used in this test method are defined in Terminol-ogy standards C125,C1180,or the other referenced ASTMstandards.4.Significance and Use4.1 This test method provides procedures for petrographicexamination and chemical analysis of mortar for componentsof masonry mortar.These components may include portlandcement,hydrated calcitic or dolomitic lime,masonry cement,aggregates,and air.4.2 The test method consists of procedures and sub-procedures,each requiring a substantial degree of petrographicand chemical skills and relatively elaborate instrumentation.4.3 The chemical data considered together with results ofpetrographic examination of a mortar provide for calculation ofcomponent proportions and thus allow a determination ofmortar composition as represented by Types M,N,S,and O inTable 1(Proportion Specification Requirements)of Specifica-tion C270.4.4 Failure of a mortar to have the composition of any typeas defined in Table 1 of Specification C270 does not necessar-ily mean that the mortar does not meet the requirements ofSpecification C270.The mortar may meet the alternativerequirements of Table 2(Property Specification Requirements)of Specification C270.1This test method is under the jurisdiction ofASTM Committee C12 on Mortarsand Grouts for Unit Masonry and is the direct responsibility of SubcommitteeC12.02 on Research and Methods of Test.Current edition approved Dec.1,2015.Published January 2016.Originallyapproved in 2002.Last previous edition approved in 2010 as C1324 10.DOI:10.1520/C1324-15.2For 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 4.5 The maleic acid method of analysis is not applicable forthe analysis of mortar because it is greatly influenced bycarbonation and does not provide for the determination ofcalcium.5.Qualifications of Petrographer and Chemist5.1 Petrographer:5.1.1 The petrographic examination requires the skill of apetrographer well versed in the petrographic methods ofPractice C856,Test Method C457,and Guide C295,and in theevaluations of portland cement-containing materials and ofmasonry mortars.5.1.2 The interpretation and evaluation of the p
