Description / Abstract:
This method covers the determination of specific gravity and
absorption of coarse aggregate. The specific gravity may be
expressed as bulk specific gravity, bulk specific gravity
(saturated surface-dry (SSD)), or apparent specific gravity. The
bulk specific gravity (SSD) and absorption are based on aggregate
after 15–19 h of soaking in water. This method is not intended to
be used with lightweight aggregates.
The values stated in SI units are to be regarded as the
standard.
This standard may involve hazardous materials, operations,
and equipment. This standard does not purport to address all of the
safety concerns associated with its use. It is the responsibility
of the user of this standard to consult and establish appropriate
safety and health practices and determine the applicability of
regulatory limitations prior to use.
