Description / Abstract:
This test method covers determination of the fineness of
portland cement as represented by a calculated measure of specific
surface, expressed as square centimeters of total surface area per
gram, or square meters of total surface area per kilogram, of
cement, using the Wagner turbidimeter.
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 and
health practices and determine the applicability of regulatory
limitations prior to use.
The values stated in either SI units or inch-pound units are to
be regarded separately as standard. The values stated in each
system may not be exact equivalents; therefore, each system shall
be used independently of the other. Combining values from the two
systems may result in nonconformance with the standard. Values in
SI units (or inch-pound units) shall be obtained by measurement in
SI units (or inch-pound units) or by appropriate conversion, using
the Rules for Conversion and Rounding given in IEEE/ASTM SI 10 of
measurements made in other units. Values are stated in SI units
when inch-pound units are not used in practice.
