    1、Designation: C 51 07Standard Terminology Relating toLime and Limestone (as used by the Industry)1This standard is issued under the fixed designation C 51; the number immediately following the designation indicates the year of originaladoption or, in the case of revision, the year of last revision. A

    2、 number in parentheses indicates the year of last reapproval. A superscriptepsilon (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.1. Scope*1.1 This terminology refers to the terms relating to li

    3、me andlimestone products as used by the industry.1.2 Where appropriate, the various terms defined belowshould be prefixed with one or other of the adjectives “high-calcium,” “magnesian,” or “dolomitic.” (Examples: dolomiticquicklime; high-calcium hydraulic hydrated lime; magnesianor dolomitic limest

    4、one.)1.3 The composition of a limestone should be given in termsof a percentage of the carbonates present. In limestone ofinterest to the lime industry, it is usually assumed that thematerial consists almost entirely of carbonates. Where thisassumption is not valid, the percentage of noncarbonate ma
