A soil sample has avoid ratio of 0.72, moisture content = 12% and Gs=2.72 determine the following: a)Dry unit weight, moist unit weight (KN/m3). b)Weight of water in KN/m3 to be added for 80% degree of saturation. c)Is it possible to reach a water content of 30% without change the present void ratio. d)Is it possible to compact the soil sample to a dry unit weight of 23.5 KN/m3.
