A soil has porosity of 40% and air content of 50%.What will be its percentage air voids?

Civil Engineering : Soil Mechanics - Quiz(MCQ)

20%

30%

50%

60%

Correct Answer : 20%

Explanation : Porosity n = 40% = 0.4
Air content a_c = 50% = 0.5
Percentage air voids na= n*a_c
na = 0..4*0.5
na = 20%.
