A number in parenthes
2、es indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope*1.1 This terminology defines terms relating to hydraulic cements, their components, characteristics, properties, and the testingthereof. Some terms may have
3、wider application than just to hydraulic cement.1.2 See individual standards for terms applicable primarily therein, including meanings that may be more restrictive than thosegiven here, and for explanations and descriptions of terms as they apply to those standards.1.3 This standard does not purpor
4、t to address all of the safety concerns, if any, associated with its use. It is the responsibilityof the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatorylimitations prior to use.2.
