◆ Problem 8 A soil has a bulk density of 1.91 Mg/m3 and a water content of 9.5%. The value of Gs is 2.70. Calculate the void ratio and degree of saturation of the soil. What would be the values of density and water content if the soil were fully saturated?

A specimen of clay has a water content of 82% and a saturation of 95%. The specific gravity of solids is 2.76. What is the void ratio of this soil? What is the moist density of this soil in kg/m3? Round the answers to five significant figures. Include phase diagram(s).

4. A soil sample has a bulk unit weight of 19.6 kN/m³ and a water content of 10%. The value of Gs (i.e. the specific gravity of soil grains) is 2.70. Calculate the void ratio and degree of saturation of this sample. What would be the values of unit weight and water content if the soil were fully saturated at the same void ratio?
