Answer:
- Moisture/ water content w = 26%
- Void ratio , e = 0.73
Explanation:
- Initial mass of saturated soil w1 = mass of soil - weight of container
= 113.27 g - 49.31 g = 63.96 g
- Final mass of soil after oven w2 = mass of soil - weight of container
= 100.06 g - 49.31 g = 50.75
Moisture /water content, w = =
= 0.26 = 26%
Void ratio = water content X specific gravity of solid
= 0.26 X 2.80 =0.728
