1、Designation: C10/C10M 10C10/C10M 13Standard Specification forNatural Cement1This standard is issued under the fixed designation C10/C10M; 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 parent
2、heses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope*1.1 This specification covers natural cement and quick-setting natural cement.NOTE 1Examples of typical past uses of natural cement include unit masonry m
3、ortar, cement plaster, grout, whitewash, and concrete.1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in eachsystem may not be exact equivalents; therefore, each system shall be used independently of the other. Combining value
4、s from thetwo systems may result in non-conformance with the standard. Values in SI units or inch-pound units shall be obtained bymeasurement in SI units or inch-pound units or by appropriate conversion, using the Rules for Conversion and Rounding givenin IEEE/ASTM SI 10, of measurements made in oth
5、er units or SI units. Values are stated in only SI units when inch-pound unitsare not used in practice.1.3 The text of this standard references notes and footnotes which provide explanatory material.
