Question

A soil sample has a porosity of 40% specific gravity is 2.70calculate void ratio dry density​

Answer 1

Answer:

Void ratio of soil sample is the ratio of the volume of soil solids in the given mass of soil.

The porosity of soil sample is the ratio of the volume of voids to the total volume of the given mass of soil.

Given details:

Porosity of the soil sample is 40%. So, n = 0.4

Specific gravity of solids is 2.7

Required Formula:

Void ratio (e) = n/(1-n)

Solution:

e = 0.4 / (1-0.4)

e = 0.6667
