1、Designation: C114 11b1Standard Test Methods forChemical Analysis of Hydraulic Cement1This standard is issued under the fixed designation C114; 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 p

Scope*1.1 These test methods cover the chemical analyses ofhydraulic cements. Any test methods of demon
3、strated accept-able precision and bias may be used for analysis of hydrauliccements, including analyses for referee and certificationpurposes, as explained in Section 4. Specific chemical testmethods are provided for ease of reference for those desiring touse them. They are grouped as Reference Test
4、 Methods andAlternative Test Methods. The reference test methods are longaccepted classical chemical test methods which provide areasonably well-integrated basic scheme of analysis for hy-draulic cements. The alternative test methods generally provideindividual determination of specific analytes and

Description of Referee Analyses4.1 Referee AnalysesWhen conformance to chemicalspecification requirements is questioned, perform refereeanalyses as described in 4.1.1. The reference test methods thatfollow in Sections 7-22,
17、or other test methods qualifiedaccording to 5.4, the Performance Requirements for Rapid TestMethods Section, are required for referee analysis. A cementshall not be rejected for failure to conform to chemicalrequirements unless all determinations of constituents involvedand all necessary separations
18、 prior to the determination of anyone constituent are made entirely by these methods. Whenreporting the results of referee analyses, specify which testmethods were used.4.1.1 Referee analyses shall be made in duplicate and theanalyses shall be made on different days. If the two results donot agree w
19、ithin the permissible variation given in Table 1, thedetermination shall be repeated until two or three results agreewithin the permissible variation. When two or three results doagree within the permissible variation, their average shall beaccepted as the correct value. When an average of either tw
20、o orthree results can be calculated, the calculation shall be based onthe three results. For the purpose of comparing analyses andcalculating the average of acceptable results, the percentagesshall be calculated to the nearest 0.01 (or 0.001 in the case ofchloroform-soluble organic substances), alth
21、ough some of theaverage values are reported to 0.1 as indicated in the testmethods.
