The specific gravity of fine aggregate (sand) is considered to be around 2.65 to 2.67. 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

Crushing Value Test of Aggregates – Importance, Procedure, and Standard limits. The aggregate crushing value test on coarse aggregates gives a relative measure of an aggregate under a gradually applied compressive load. It is a numerical index of the strength of the aggregates. This test is helpful in the construction of roads and pavements.
