The densities of rocks and minerals are normally expressed as specific gravity, which is the density of the rock relative to the density of water. This isn''t as complex as you may think because water''s density is 1 gram per cubic centimeter or 1 g/cm 3. Therefore, these numbers translate directly to g/cm 3, or tonnes per cubic meter (t/m 3).

Specific Gravity is the ratio of the weight of a given volume of aggregate to the weight of an equal volume of water. Water, at a temperature of 73.4°F (23°C) has a specific gravity of 1. Specific Gravity is important for several reasons. Some deleterious particles are lighter than the good aggregates.

Fine aggregate Specific gravity or Specific gravity of sand is the ratio of the weight of a given volume of fine aggregate (sand) to the weight of an equal volume of water. The Fine aggregate Specific gravity is often considered to be 2.65. For road construction, fine aggregate has a wide range from about 2.5 -3.0 but on average 2.68.

Measure the increase in volume caused by the dry solids displacing some of the water. Assume the new volume is 550 c.c. The displacement, then, is 50 c.c. (550-500). Divide the weight of the dry solids (200 gr.) by the difference in volume (50 c.c.). The result, 4.00, is the specific gravity of the dry solids.

As specific gravity is just a comparison, it can be applied across any units. The density of pure water is also 62.4 lbs/cu.ft (pounds per cubic foot) and if we know that ammonium nitrate has a sg of 0.73 then we can calculate that its density is 0.73 x 62.4 = 45.552 lbs/cu.ft.
