Standard Specification for
Coarse Aggregate for
Hydraulic Cement Concrete
SCOPE
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 1–This 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.
