2. The field unit weight of the soil sample 1s 1960 kg/m3 and the unit weight of the soil particle is 2700 kg/ m. If the emax = 0.69 and emin = 0.44, determine the following: a) Specific gravity b) Dry unit weight if water content is 15% c) Porosity d) Relative density e) Saturated unit weight f) Effective unit weight g) Weight of water in KN that must be added per m3 for a 90%-degree saturation h) Mass of water in kg to be added per 2.5m3 to reach full saturation i) If max dry unit weight is 18KN/m³, what is the percentage compaction? j) Is it within the allowable compaction range of 95 of relative +0.2?
3 The moist unit weight of a soil is 19.2 KN/m^3. Given that Gs = 2.69 and w = 9.8%. Determine: Void Ratio, Dry Unit Weight, and the Degree of Saturation 4. A soil sample has a unit weight of 105.7 pcf (Pounds per Cubic Foot) and a saturation of 50%. When the saturation is increased to 75%, its unit weight raises to 112.7 pcf. Determine the void ratio and the specific gravity of the soil
EX.1 A soil sample has a unit weight of (1.9gm/cc) and the water content=12%, if Gs=2.65, determine: dry unit weight, degree of saturation, void ratio, porosity. EX.2 A partially saturated soil has a volume of (6x10*m³) and weight of (0.902N). The sample is dried in an oven and its dried weight is (0.724N), if specific gravity is (2.6), find degree of saturation. EX.1 The mass of moist soil sample collected from the field is 465gm, and its oven dry mass is 405.76 gm. The specific gravity of the soil solids was determined in the laboratory to e 2.68. If the void ratio of the soil in the the following: 1. The moist density of the soil in the field (Kg/m³) 2. The dry density of the soil in the field (Kg/m³) tural state is 0.83, find 3. The mass of water, in kilograms, to be added in cubic meter of soil in the field for saturation
Situation 5 : A sample of saturated clay was placed in a container and weighed. The weight was 6N. The clay in its container was placed in an oven dray for 24 hours @ 105℃. The weight reduced to a constant weight of 5N. The weight of the container is 1N. If Gs = 2.7, determine: a. Water content b. Void ratio c. Moist unit weight d. Dry unit weight f. Effective unit weight
