This specification  covers coarse aggregate, other than lightweight  aggregate,  for use in concrete.

Several classes and gradings of coarse aggregate  are described (Notes  1   and 2).

Note 1This specification  is regarded as adequate to ensure satisfactory materials for most concrete. It is recognized  that, for certain work or in certain regions, it may be either more or less restrictive than needed.

Note 2-Definitions of terms used in this specification  may be found in ASTM C 125.

The values stated in SI units are to be regarded  as the standard.
