A cube of dried clay having sides 4 cm long has a mass of 110 gms. The same cube of soil, when saturated at unchanged volume has a mass of 135 gms. Draw a phase diagram showing the constituents of volumes and weights and then determine the specific gravity of soil solids and the void ratio.

A soil sample has a natural water content of 20.6% and it is known to have Gs of 2.6.In order to determine the density of a soil, a portion of soil weighing 222 g is put in a 500 cm³ container. It is filled with 377 cm³ of water to fill the container. a) Determine the moist unit weight of the soil in kN/m³. b) Determine the dry unit weight of the soil in kN/m³.c) Determine the void ratio

8. A sample of soil has a water content w= 14.7%, and a cube of dimensions 10 cm x 10 cm × 10 cm weighs 18.4 N. The grain specific gravity Gs = 2.72. Calculate the unit weight, the void ratio and the degree of saturation. What would be the unit weight and the water content if the soil had the same void ratio, but was saturated? What would be the unit weight if the soil had a water content of zero?
