(Terminology)Standard Terminology Relating to Concrete and Concrete Aggregates
Standard Terminology Relating to Concrete and Concrete Aggregates
SCOPE
1.1 This standard is a compilation of general terminology related to hydraulic cement concrete, concrete aggregates, and other materials used in or with hydraulic cement concrete.
1.2 Other terminology under the jurisdiction of Committee C09 is included in two specialized standards. Terms relating to constituents of concrete aggregates are defined in Descriptive Nomenclature C 294. Terms relating to constituents of aggregates for radiation-shielding concrete are defined in Descriptive Nomenclature C 638.
1.3 Related terminology for hydraulic cement is included in Terminology C 219. Additional related terminology can be found in ACI 116R.
1.4 When a term is used in an ASTM standard for which Committee C09 is responsible, it is included herein only if used in more than one Committee C09 standard.
1.5 Definitions that are adopted from those published by other ASTM committees or other standards organizations are identified with the ASTM designation (for example, Terminology C 219) or with the abbreviation of the name of the other organization.
1.6 A definition in this standard is a statement of the meaning of a word or word group expressed in a single sentence with additional information included in notes or discussion.Note 1
The subcommittee responsible for this standard will review definitions on a five-year basis to determine if the definition is still appropriate as stated. Revisions will be made when determined necessary.
