1) Question.
If the volume of voids is equal to the volume of solids in a soil mass, then the values of porosity and voids ratio respectively are
Answer.
-
2) Question.
Voids ratio of a soil mass can
Answer.The void ratio (e) is defined as: e=Vv/Vs
where:- Vv= Volume of voids
- Vs= Volume of solids
Since both Vv and Vs are positive:
- Void ratio cannot be negative.
- In real soils, e > 0.
- There is no upper limit. Very loose soils, peat, and organic soils can have e > 1, 2, or even higher.
