The in-situ percentage of voids in a sand deposit is 40%. If the maximum and minimum dry densities of sand as determined from laboratory tests are 2.2 and 1.45 g/cm3 respectively, determine the density index. Assume specific gravity of sand particles is 2.65.

We know that

The in situ dry density of a sand is 1.68 Mg/m3. The maximum and minimum dry densities, determined by standard laboratory tests, are 1.84 Mg/m3 and 1.47 Mg/m3, respectively. Determine the relative density of the sand. The particle specific gravity of the sand is 2.65. (Density of water 1 Mg/m3)
