SPECIFIC GRAVITY TEST OF SOIL(IS-2720-PART-3-1980)

Is code for specific gravity by Pycnometer?

To determine the specific gravity of soil solids by Pycnometer bottle method. 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 distilled water at a stated temperature. Specification: This test is specified in IS: 2720 (Part 4) – 1985.

What should be the specific gravity of fine aggregate?

Specific gravity of fine aggregate (sand) is defined as the ratio of the weight of a given volume of aggregates to the weight of equal volume of water. The specific gravity of fine aggregate (sand) is considered to be around 2.65 to 2.67.
