SCOPE 1.1. This method covers the determination of bulk and apparent specific gravity 23/23C (73.4/73.4F) and absorption of fine aggregate. 1.2. This method determines (after 15-19 h of soaking in water)the bulk specific gravity and the apparent specific gravity the bulk specific gravity on the basis of mass of saturated surface-dry (SSD)aggregate and the absorption. 1.3. The values stated in SI units are to be regarded as the standard. 1.4. 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 procedure to consult and establish appropriate safety and health practices and to determine the applicability of regulatory limitations prior to its use. 1.5. The quality of the results produced by this standard are dependent on the petence of the personnel performing the procedure and the capability calibration and maintenance of the equipment used.Agencies that meet the criteria of R 18 are generally considered capable of petent and objective testing/sampling/inspection/etc.Users of this standard are cautioned that pliance with R 18 alone does not pletely assure reliable results.Reliable results depend on many factors;following the suggestions of R 18 or some similar acceptable guideline provides a means of evaluating and control...
