Question

A dry soil sample has equal amounts of solids and voids by volume. Its void ratio and porosity will be

Void ratio Porosity (%)

(a) 1.0 100%

(b) 0.5 50%

(c) 0.5 100%

(d) 1.0 50%

• A. (a) 1.0 100%
• B. (b) 0.5 50%
• C. (c) 0.5 100%
• D. (d) 1.0 50%

Answer 1

The correct option is D (d) 1.0 50%

(d)

$Voidratio,e=\frac{V_V}{V_s}=1$

$Porosity,n=\frac{e}{1+e}\times 100=\frac{1}{1+1}\times 100$

= 50%
