As with many porous material, the value obtained for the particle density of an aggregate will depend on the method of test and apparatus used. Different particle sizes within a sample often have different particle densities. The termparticle density expressed in Mg/m³ is numerically equal to the specific gravity. Various methods, depending upon the type and size of material to be tested, are specified in standards for testing aggregate.

Manufactured from heavy gauge steel these bulk density measures comply with the requirements of either BS 812 or ASTM C-29. Other than the 3 litre size, all measures incorporate carrying handles as standard.

Method for aggregate 20 mm and smaller The gas jar method described in BS 812 is suitable for all aggregates smaller than 20 mm in size and is particularly suited to friable aggregates. The pyknometer method described in ASTM C128 is suitable for determining the particle density of samples of fine aggregates. The particle density of fillers can be determined using the density bottle method specified for testing cement.
