1、Designation: C219 14Standard Terminology Relating toHydraulic Cement1This standard is issued under the fixed designation C219; 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 indic

2、ates 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 hydrauliccements, their components, characteristics, properties, and thetesting thereof. Some terms may have wider app
