Title
Standard Test Method for Density, Relative Density (Specific Gravity), and Absorption of Fine Aggregate
ASTM International
Publication Date:
Aug 1, 2007
Scope:
This test method covers the determination of the average density
of a quantity of fine aggregate particles (not including the volume
of voids between the particles), the relative density (specific
gravity), and the absorption of the fine aggregate. Depending on
the procedure used, the density, in
kg/m3(lb/ft3) is expressed as oven-dry (OD),
saturated-surface-dry (SSD), or as apparent density. Likewise,
relative density (specific gravity), a dimensionless quality, is
expressed as OD, SSD, or as apparent relative density (apparent
specific gravity). The OD density and OD relative density are
determined after drying the aggregate. The SSD density, SSD
relative density, and absorption are determined after soaking the
aggregate in water for a prescribed duration.
This test method is used to determine the density of the
essentially solid portion of a large number of aggregate particles
and provides an average value representing the sample. Distinction
is made between the density of aggregate particles as determined by
this test method, and the bulk density of aggregates as determined
by Test Method C 29/C 29M, which includes the volume of voids
between the particles of aggregates.
This test method is not intended to be used for light-weight
aggregates.
The values stated in SI units are to be regarded as the standard
for conducting the tests. The test results for density shall be
reported in either SI units or inch-pound units, as appropriate for
the use to be made of the results.
The text of this test method 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 test method.
This standard does not purport to address all of the safety
concerns, if any, associated with its use. It is theresponsibility
of the user of this standard to establish appropriate safety and
health practices and determine the applicability of regulatory
limitations prior to use.
*A Summary of Changes section appears at the end of this
