Title
Standard Specification for Concrete Aggregates
ASTM International
Publication Date:
Dec 1, 2008
Scope:
This specification defines the requirements for grading and
quality of fine and coarse aggregate (other than lightweight or
heavyweight aggregate) for use in concrete.2
This specification is for use by a contractor, concrete
supplier, or other purchaser as part of the purchase document
describing the material to be furnished.
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. For example, where aesthetics are
important, more restrictive limits may be considered regarding
impurities that would stain the concrete surface. The specifier
should ascertain that aggregates specified are or can be made
available in the area of the work, with regard to grading,
physical, or chemical properties, or combination thereof.
This specification is also for use in project specifications to
define the quality of aggregate, the nominal maximum size of the
aggregate, and other specific grading requirements. Those
responsible for selecting the proportions for the concrete mixture
shall have the responsibility of determining the proportions of
fine and coarse aggregate and the addition of blending aggregate
sizes if required or approved.
The values stated in either SI units or inch-pound units are to
be regarded separately as standard. The values stated in each
system may not be exact equivalents; therefore, each system shall
be used independently of the other. Combining values from the two
systems may result in non-conformance with the standard.
The text of this standard references notes and footnotes which
provide explanatory material. These notes and footnotes (excluding
those in tables and figures) shall not be considered as
requirements of this standard.
2 For lightweight aggregates, see Specifications C
330, C 331, and C 332; for heavyweight aggregates see Specification
C 637 and Descriptive Nomenclature C 638.
