Specific Gravity of Fine Aggregate as per IS 2386 Part-3 (1963

Sand particles composed of quartz have a specific gravity between 2.65 to 2.67.While inorganic clays generally range from 2.70 to 2.80.Soils with large amounts of organic matter or porous particles (such as diatomaceous earth) have specific gravity below 2.60 (Some range as low as 2.00).
