1.1 This test method covers the determination of the average density of a quantity of coarse aggregate particles (not including the volume of voids between the particles) the relative density (specific gravity) and the absorption of the coarse aggregate. Depending on the procedure used the density (kg/m³ (lb/ft³)) is expressed as oven-dry (OD) or as apparent density. Likewise relative density (specific gravity) 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.

1.2 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.

1.3 This test method is not intended to be used with lightweight aggregates.

1.4 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.

1.5 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 practice provides standard requirements for evaluating frost-susceptible coarse aggregate in air-entrained concrete subjected to freezing and thawing in accordance with Test Method C 666/C 666M.

The Micro-Deval abrasion test is a test of coarse aggregate to determine abrasion loss in the presence of water and an abrasive charge. Many aggregates are more susceptible when wet than dry and the use of water in this test incorporates this reduction in resistance in degradation in contrast to some other tests which are conducted on dry aggregate. The test results are helpful in evaluating the toughness/abrasion resistance of coarse aggregate subject to abrasion when adequate information is not available from service records.

The Micro-Deval abrasion test is useful for detecting changes in properties of aggregate produced from an aggregate source as part of a quality control or quality assurance process.
