| A2.3. Significance and Use
A2.3.1 This annex provides a means to determine the amount of methylene blue dye adsorbed by a sample of finely ground limestone. Methylene blue dye is preferentially adsorbed by clay minerals that may be present in limestone. The amount of dye adsorbed is related to the clay type and content. Certain clays may increase the water demand or affect other properties of cements if present in sufficient quantity in the limestone when used as an ingredient in cement. The specification places a limit on the methylene blue index of limestone permitted as an ingredient in blended cement. |

|
1.1 This specification pertains to blended hydraulic cements for both general and special applications, using slag, pozzolan, limestone, or some combination of these, with portland cement or portland cement clinker or slag with lime. 1.2 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
non-conformance 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 [or SI units]. Values are stated in only SI
units when inch-pound units are not used in practice.
1.3 The text of this standard refers to notes and footnotes which provide explanatory material. These notes and footnotes (excluding those in tables and figures) are not requirements of the standard. |
