A sample of soil was tested; the results were
void ratio e = 1.024
moisture content w = 33.4%
specific gravity of solids Gs = 2.75

Using a phase diagram, determine the following:
a) The soil's bulk, dry and saturated unit weights, and degree of saturation;
b) The volume of air void in 1m^3 of this soil; and
c) The weight of water required to fully saturate the 1m^3 soil

Solutions

Expert Solution

Degree of saturation

Degree of saturation

Degree of saturation = 89.69%

Bulk Unit weight of soil

Bulk unit weight of soil

Unit weight of water = 9.81kN/m3

Bulk unit weight of soil = 17.78kN/m3

Dry Unit Weight of soil

Dry Unit weight of soil = 13.328 kN/m3

Saturated Unit weight

Saturated unit weight of soil = 18.291 kN/m3

Volume of air void in 1m3= porosity

= 50.59 %

Volume of air void in 1m3 = 0.5059 m3

Degree of saturation

Fully saturated means

Weight of water required =

Weight of water required
