Question

2) A soil sample has a unit weight of 16.9kN/m ^3 and a saturation of 50%. When its saturation increased to 75%, its unit weight raises to 18kN/m ^3 . Determine the void ratio and the specific gravity of this soil.

Answer 1

Void ratio (e) for initial conditions: 0.44

Void ratio (e) for final conditions: 0.67

Specific gravity (G): 2.78
