Air Content –

Defined how Much volume of air present in the pores of soil as compared to total voids volume in the soil mass.

the value of air content is zero when the soil is fully saturated because of no air present in the fully saturated soil.

Air content (ac) = Va / Vv

Percentage air voids –

its defined how much percentage of air is present as compare to total volume in a soil mass.

denoted by (na) = Va / V

The relation between air content and percentage Air Voids.

relation between air content and percentage air void

from above relation, we can say percentage air voids is equal to porosity multiply air content.
