A dry soil has mass specific gravity of 1.35. If the specific gravity of solids is 2.7, then the void ratio will be
Gm=Gs(1−n)=Gs1+e
Gm is mass specific gravity
Gs is specific gravity of solids
∴e=GsGm−1
⇒e=GsGm−1=1
A sample of saturated sand has a dry unit weight of 18kN/m3 and a specific gravity of 2.7. If density of water is 10kN/m3, the void ratio of the soil sample will be
