The water content of a saturated soil and the specific gravity of soil solids were found to be 30% and 2.70, respectively, Assuming the unit weight of water to be 10 kN/m3, the saturated unit weight (kN/m3) and the void ratio of the soil are
-
- 19.4, 0.81
- 18.5, 0.30
- 19.4, 0.45
- 18.5,0.45
Correct Option: A
w = 0.3
G = 2.7
Sr = 1 (∵ it is saturated soil)
We know,
| e = | = | = 0.81 | ||
| Sr | 1 |
Saturated unit weight,
| γsat = | 1 + e |
| = | 1 + .81 |
= 19.39 kN/m3.
