C= Weight of pycnometer containing the sample and filled with water. D= Dry weight. Part C (Specific Gravity and Absorption for sand)
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.

The specific gravity of a blended aggregate is not simply the weighted average of the specific gravities of the individual components. To derive an appropriate equation, let's assume a blend of two aggregates (A and B). The weight of the blend is given by. Let GA, GB, and Gblend be the specific gravities of materials A and B and the blend.
Scope. 1.1 These test methods cover the determination of the specific gravity of soil solids that pass the 3 / 8 -in. (9.5-mm) or smaller sieve by means of the water displacement method. When the total sample contains larger particles, it is separated into a coarser and finer portion using a 3 / 8 -in. (9.5-mm) or No. 4 (4.75-mm) or finer sieve.

5.1 Relative density (specific gravity) is the ratio of mass of an aggregate to the mass of a volume of water equal to the volume of the aggregate particles – also referred to as the absolute volume of the aggregate. It is also expressed as the ratio of the density of the aggregate particles to the density of water. Distinction is made between the density …

5.1 Density is a key element in the phase relations, phase relationships, or mass-volume relationships of soil and rock (Appendix X1).When particle density, that is, specific gravity (Test Methods D854) is also known, dry density can be used to calculate porosity and void ratio (see Appendix X1).Dry density measurements are also useful for …
Specific gravity is the ratio of the object's density to the density of water, i.e.: The units cancel out in the ratio. Therefore, the specific gravity is a unitless number. The density of water is 1.0 g/mL at room temperature, so the specific gravity is equal to the density of the object expressed without a unit.
Specific Weight. The specific weight of a substance is the weight per unit volume. Specific weight is usually given the symbol (gamma) ("gamma") and can be calculated as the product of density times the local acceleration of gravity: [gamma=rho g nonumber ] Any values of specific weight you find listed in a table have, of necessity, assumed a …
Density is an important parameter for sand. For sand, density is determined by multiplying the relative density (specific gravity) of the sand times the density of water. Bulk Density of Sand. The bulk density or unit weight of sand is the mass or weight of the sand that required to fill a container of a specified unit volume.

Divide the weight by the volume (1,000 ml) to find the density of the sand. For example, if the sand weighs 1,500 grams, the density is 1.5. Subtract the density of the sand from the specific gravity of the sand, then divide the result by the specific gravity to find the voidage (proportion of empty space in the dry sand).
