EXPERIMENT 4 SPECIFIC GRAVITY DETERMINATION Purpose: This lab is performed to determine the specific gravity of soil by using a pycnometer. Specific gravity is the ratio of the mass of unit volume of soil at a stated temperature to the mass of the same volume of gas-free
Specific Gravity is the ratio of the weight of a given volume of aggregate to the weight of an equal volume of water. It is the measure of strength or quality of the specific material. Aggregates having low specific gravity are generally weaker than those with higher specific gravity values.
What is required to make this measurement is a weight scale, and the list of the different minerals SPECIFIC GRAVITIES. What specific gravity is, is the mass of a solid in relationship to its weight. An extreme example of this is the difference in volume of a pound of feathers and a pound of gold.
Procedure to Determine the Specific Gravity of Fine-Grained Soil i) The density bottle along with the stopper, should be dried at a temperature of 105 to 110 o C, cooled in the desiccator and weighed to the nearest 0.001g (W 1).

Specific gravity of soil at ___ 0 C = _____. Unless specified, the specific gravity values of the soil will be reported at 27-degree Celsius. The specific gravity of soil particles will come within the range of 2.65 and 2.85. If the soils consist of porous and organic materials, a specific gravity …
Typical minerals, gravels, sands and earth - weights and specific density - convert tons of gravel into cubic yards, or sand or dirt, etc.
That will give you the specific gravity of the sand. Because you divide densities, the units cancel out, and specific gravity does not have any units. For example, you determine the density of the sand to be 10g/cm 3 , and the density of pure water is known to be 1g/cm 3 . Divide 10g/cm 3 by 1g/cm 3 .

The specific gravity is the ratio between the density of an object, and a reference substance. The specific gravity can tell us, based on its value, if the object will sink or float in our ...
If it is a predominantly quartz sand, the specific gravity of the grains will be about 2.65 g/cm^3. Carbonate sands are composed of minerals with a specific gravity of 2.71 g/cm^3 but the grains are frequently porous and consequently will have a lower specific gravity.

Sand is composed of fine granular particles that soak up water easily, so its wet-weight density differs from its dry. Specifically, the dry density of sand is 100 lbs per cubic foot while wet sand has a weight density of 120–130 lbs per cubic foot (See Reference 2).
The specific gravity of quartz is 2.65, but sand is porous. A good approximation is 1.6 for compacted sand where the interstitial volume i … s filled with air, rising to 1.9 when the sand is saturated with water.

S = specific gravity of slurry Si= specific gravity of liquid phase Ss= specific gravity of solids phase Cw = concentration of solids by weight Cv= concentration of solids by volume EXAMPLE: if the liquid has a specific gravity of 1.2 and the concentration of solids by weight is 35% with the solids having a specific gravity of 2.2, then:
In physics, a substance’s specific gravity is the ratio of that substance’s density to the density of water at 4 degrees Celsius. Because the density of water at 4 degrees Celsius is 1,000 kg/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.

In Imperial or US customary measurement system, the Sand, Silica density is equal to 96.01 pound per cubic foot [lb/ft³], or 0.89 ounce per cubic inch [oz/inch³] . Sand, Silica density is equal to 1538 kg/m³ or 96.014 lb/ft³ with specific gravity of 1.538 relative to pure water.
Significance of specific gravity of cement; Experiment to determine this value . What is Specific Gravity of Cement? Definition – Specific Gravity is just a comparison between the weight of a volume of a particular material to the weight of the same volume of water at a specified temperature.
The specific gravity of all other materials are compared to water as a fraction heavier or fraction lighter density, no matter how small or large the fraction is. For example, ammonium nitrate has a specific gravity (sg) of 0.73 while dry ammonium sulphate has a sg of 1.13 (1130 kilograms/cubic meter).

Therefore, the specific gravity of soil solids containing extraneous matter, such as cement, lime, and the like, water-soluble matter, such as sodium chloride, and soils containing matter with a specific gravity less than one, typically require special treatment (see Note 1) or a qualified definition of their specific gravity.
