Lime and Limestone (as used by the Industry)
This standard is issued under the fixed designation C 51; the number immediately following the designation indicates the year of original
adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A superscript
epsilon (e) indicates an editorial change since the last revision or reapproval.
This standard has been approved for use by agencies of the Department of Defense.
INTRODUCTION
Where appropriate, the various terms defined below should be prefixed with one or other of the
adjectives “high-calcium,” “magnesian,” or “dolomitic.” (Examples: dolomitic quicklime; high-
calcium hydraulic hydrated lime; magnesian or dolomitic limestone.)
The composition of a limestone should be given in terms of a percentage of the carbonates present.
In limestone of interest to the lime industry, it is usually assumed that the material consists almost
entirely of carbonates. Where this assumption is not valid, the percentage of noncarbonate material
should be determined, and the composition expressed in terms of the carbonate material present.
This terminology is as commonly used by the industry. For specific application of lime or a
limestone product, see the appropriate ASTM specification.
