Upload NowRelative density of cohesionless soils is defined as the ratio of the difference between the void ratio of a cohesion- less soil in the loosest state and in-situ void ratio to the difference between its void ratios in the loosest and the densest states. Thus relative density (Dr), also called density index (Id), is defined […]

How to Determine Specific Gravity of Soils ?
Article shared by :
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 […]
How to Determine the In-Situ Density of Soils ?
Article shared by :
It is often required to determine the density of soil in the natural state (in-situ density). There are several methods available for the determination of in-situ density. Two commonly used methods are: 1. Core Cutter Method 2. Sand Replacement Method. 1. Core Cutter Method: Core cutter method is used to determine the in-situ density of […]
