Example 1: A soil has void ratio = 0.72, moisture content = 12% and Gs= 2.72. Determine its
(a) Dry unit weight
(b) Moist unit weight, and the
(c) Amount of water to be added per m3 to make it saturated.
Use

Solution:

(a) = 15.51 kN/m3

(b)
        = = 17.38 kN/m3
(c) =

           = = 19.62 kN/m3

Water to be added per m3 to make the soil saturated
     = = 19.62 17.38 = 2.24 kN
