There are two basic methods of determining specific gravity of soils: 1. Pycnometer method 2. Density bottle method. 1. Pycnometer Method: Pycnometer method is used to determine the specific gravity of coarse-grained soils. Apparatus: In this method, a pycnometer of 900-mL capacity is used for determination of specific gravity. However, IS – 2720 (Part 3/sec […]
