Scope of standard 1.1 These test methods cover the chemical analyses of hydraulic cements. Any test methods of demonstrated acceptable precision and bias may be used for analysis of hydraulic cements, including analyses for referee and certification purposes, as explained in Section 3. Specific chemical test methods are provided for ease of reference for those desiring to use them. They are grouped as Reference Test Methods and Alternative Test Methods. The reference test methods are long accepted classical chemical test methods which provide a reasonably well-integrated basic scheme of analysis for hydraulic cements. The alternative test methods generally provide individual determination of specific components and may be used alone or as alternates and determinations within the basic scheme at the option of the analyst and as indicated in the individual method. 1.2 Contents: SectionSubject2Referenced Documents3Number of Determinations and Permissible Variations3.1Referee Analyses3.2Optional Analyses3.3Performance Requirements for Rapid Test Methods3.4Precision and Bias4General4.1Interferences and Limitations4.2Apparatus and Materials4.3Reagents4.4Sample Preparation4.5General Procedures4.6Recommended Order for Reporting Analyses Reference Test Methods5Insoluble Residue6Silicon Dioxide6.2Cements with Insoluble Residue Less Than 1 %6.3Cements with Insoluble Residue Greater Than 1 %7Ammonium Hydroxide Group8Ferric Oxide9Phosphorus Pentoxide10Titanium Dioxide11Zinc Oxide12Aluminum Oxide13Calcium Oxide14Magnesium Oxide15Sulfur15.1Sulfur Trioxide15.2Sulfide16Loss On Ignition16.1Portland Cement16.2Portland Blast-Furnace Slag Cement and Slag Cement17Sodium and Potassium Oxides17.1Total Alkalis17.2Water-Soluble Alkalis18Manganic Oxide19Chloride20Chloroform-Soluble Organic Substances Alternative Test Methods21Calcium Oxide22Carbon Dioxide23Magnesium Oxide24Loss on Ignition24.1Portland Blast-Furnace Slag Cement and Slag Cement25Titanium Dioxide26Phosphorus Pentoxide27Manganic Oxide28Free Calcium OxideAppendices TitleAppendix X1Example of Determination of Equivalence Point for the Chloride DeterminationAppendix X2CO2 Determinations in Hydraulic Cements1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. See 6.3.2.1 and 14.4.1 for specific caution statements.
