This terminology refers to the terms relating to lime and limestone products as used by the industry. 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. For specific application of lime or a limestone product, see the appropriate ASTM specification.
