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 °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.

Relative density is used to calculate the volume occupied by the aggregate in various mixtures containing aggregate, including hydraulic cement concrete, bituminous concrete, and other mixtures that are proportioned or analyzed on an absolute volume basis. Relative density (specific gravity) is also used in the computation of voids in aggregate in Test Method C29/C29M.

Coarse Aggregate Specific Gravity Calculations Example Problem. Aggregate Blending, Absorption Specific Gravity 15 Fine Aggregate Specific Gravity • ASTM C128 – Dry aggregate – Soak in water for 24 hours – Spread out and dry to SSD – Add 500 g of SSD aggregate to pycnometer of known

Calculating Specific Gravity. The following formula is used to calculate the specific gravity of a material. SG = ρ / ρW. Where SG = specific gravity, ρ = density of the material (kg/m 3 ), ρW = density of water ( kg/m 3 ). The reference density of water at 4 o C (39 o F) is used as the reference as these are the conditions of maximum density.

Specific gravity. Specific gravity (G s) is a property of the mineral or rock material forming soil grains. It is defined as Method of measurement For fine soils a 50 ml density bottle may be used; for coarse soils a 500 ml or 1000 ml jar. The jar is weighed empty (M 1). A quantity of dry soil is placed in the jar and the jar weighed (M 2).

 · The specific gravity of water varies with temperature, however, at 4 degrees Celsius the specific gravity of water is 1.. Some people wonder why some objects float on water while others sink. The specific gravity of water is quite a complex issue and one of the best ways to understand it is by taking stock of some of the objects that float and those who sink.

NTP Normal Temperature and Pressure defined as 20 o C ( K, 68 o F) and 1 atm ( kN/m2, kPa, psia, 0 psig, 30 in Hg, 760 torr); Molecular weights can be used to calculate Specific Gravity if the densities of the gas and the air are evaluated at .

Answer (1 of 2): With liquids and solids you simply measure the mass, measure the volume, and then divide the mass by the volume. With irregular shapes the volume measurement is done by immersing them in a liquid (like Archimedes). With a gas the volume, and thus density, can be almost anything y...

Therefore, the Specific Gravity G S is calculated as: A correction is utilized to adjust the results at a reference temperature T=20°C: where K is the temperature correction factor. The Specific Gravity of soils is usually between with finer soils having higher values than coarser ones.
