Question

In a wet soil mass air, occupies one- fourth of its volume and water occupies one-half of its volume. the void ratio of this soil is:

Answer 1

The correct answer could be - 1

Void ratio is calculated as - e = Vv / Vs, where Vv is the total voids of the air and water in the soil and the Vs is the void of the soil only.

So, Vv = voids of air  + voids of water-filled in the soil.

Vv = 1/4V + 1/5V = 9/20V

Vs = V - Vv = 9/20V

e = Vv / Vs = (9/20V) / (9/20V) = 1

So, the void ratio of the soil which has 1/4th air and 1/5th water will be = 1.
