Question

Dry density of a soil sample having porosity 35% and specific gravity 2.67calculate void ratio

Answer 1

Given:

the porosity of soil (n) = 35%

specific gravity = 2.67

To Find:

void ratio(e) =?

Explanation:

we know that the relationship between void ratio and porosity is

$n = \dfrac{e}{1+e}$

$\dfrac{35}{100} = \dfrac{e}{1+e}$

100e = 35(1+e)

100e = 35 + 35e

65e = 35

e = 0.538

Thus, the void ratio is 0.538
