SITUATION 5
For loose uncompacted sand:
Dr= 40%, e(min)= 0.46, e(max)= 0.90, Gs= 2.65
The height of the soil sample (H) is equal to 2- meters.
(a) Solve the dry unit weight of the soil in kN/ cubic
meters.
(b) If the soil is compacted so that Dr = 75% what is the
decrease in thickness of the soil sample in meters.
SITUATION 6
A soil specimen has a dry unit weight equal to 16 kN/m3.
Determine the moisture content if the voids contain 60%
water and 40% air, and the specific gravity, Gs = 2.7.
