Cohesive soil is known as fine soil while cohesionless soil is known as course soil. These
materials are important to be identified for its parameters and classified accordingly in
and porosity in both cohesive and cohesionless soils.
Based on the laboratory testing on a sandy soil, the following values are obtained:
Volume = 0.78 m3
Moist mass = 1755 kg
Dry mass = 1432 kg
Specific gravity of soil solids = 2.70
Determine the following parameters:
iv) Porosity
v)Then, by assuming the same parameters of sandy soil, determine the value for emin and relative
density, Dr when the soil is having 10% of fine materials and emax = 0.79.
