Aim. To determine the relative density or density index of cohesionless soil. Theory. Relative density is also known as density index. It is defined as the ratio of difference between the void ratio of a cohesionless soil (i.e. sand) in the loosest state and any given void ratio to the difference between its void ratios in the loosest state and in the densest state.

The crushed sand is manufactured from available rock stone, and the price will vary based on material availability. It can be produced near to the construction by the raw material. Due to the lack of availability, the price of river sand is high. Silt Content. In crushed sand, the possibility of silt content is less than 2%.

The Formula for Density of Sand: The ratio of the mass of the sand to the volume of the calibrating container gives the sand density. Density = Mass of Sand / Volume of Sand. Let’s say that .015 m 3 is the volume of sand and 24 kg is the mass of sand then, 24 / .015 = 1600 kg/m 3. There are the following mean densities of the different
