1.1 This test method provides a technique incorporating a thermogravimetric analyzer to determine the mass changes of hydraulic cement upon heating in an inert gas environment. The data can be used to determine the abundance of some mineralogical components in hydraulic cement powders. 1.2 Units— The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.3 This test method is applicable to hydraulic cement powders. 1.4 The text of this standard refers to notes and footnotes that provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the standard. 1.5 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.6 Warning— Fresh hydraulic cementitious mixtures are caustic and may cause burns to skin and tissue upon prolonged exposure. The use of gloves, protective clothing, and eye protection is recommended. Wash contact area with copious amounts of water after contact. Wash eyes for a minimum of 15 min. Avoid exposure of the body to clothing saturated with the liquid phase of the unhardened material. Remove contaminated clothing immediately after exposure. 1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. ====== Significance And Use ====== 5.1 This test method is intended for use in acquiring, analyzing, and reporting thermogravimetric data obtained from hydraulic cement powders. 5.2 This test method can be used to determine the calcium carbonate content of cements with interground limestone if the calcium carbonate content of the limestone is known. 5.3 This test method can be used to determine the calcium hydroxide content of hydraulic cement powder. 5.4 This test method can be used to determine the mass loss upon heating hydraulic cement powders within a specific temperature range. 5.5 This test method can be used for qualitative and quantitative characterization, under certain conditions, of various sulfate mineral components including calcium sulfate dihydrate, calcium sulfate hemihydrate, and syngenite. 5.6 Different kinds of thermogravimetric analyzers are available with different configurations and controllers. Therefore, the parameters described should be considered as guidelines. They may be altered to conform to the instrument manufacturer’s instructions, provided the changes are noted in the report.
