The specific gravity of grains of the soil was determined in the laboratory, using a pycnometer and the following observation were noted: (i) Weight of solids (W, - W,) = 100 g (ii) W3 = 613 g (iii) W = 550 g | (a) What is the specific gravity of soil? In order to confirm the value a second (b) observation of W, was made. After evacuating the pycnometer using a vacuum pump the value of specific gravity thus obtained was 2.73. Determine the volume of air entrapped in the soil suspension when the first observation was made.

What amount of water in (gr) do we have to add to a soil sample to increase its volume to 25 cm3? We know the following information about this soil: - Soil’s specific gravity is 2.5. - Void ratio (e) is 0.5. - Moisture content is 20%. - The water density is 1 gr/cm3. Hint 1: First calculate the saturation value. Hint 2: When soil is fully saturated, if we add V1 amount of water (m3), the volume of soil will increase directly by V1 (m3).
