A sample of soil compacted according to the standard Proct or test has a density of 2.06 g/cm³ at 100% compaction and at an optimum water content of 14%. What is the dry unit weight? What is the dry unit weight at zero air-voids? If the voids become filled with water what would be the saturated unit weight? Assume Gs = 2.67 Air Water Solids Ma + + M, M *+ Ww

A soil sample was compacted. The result of the standard proctor test shows that at 100% compaction, the soil weighs 132.3 pcf with optimum moisture content of 14%. Gs = 2.67 a) What is the saturated unit weight of the soil in pcf? b) What is the maximum dry unit weight of the soil (at zero air voids) in pcf?

A soil specimen has a total volume of 70 cm3 and a total mass of 135.5g. After complete drying in an oven, the specimen has a mass of 122.0g. The Gs is 2.60. Determine the void ratio. Report your answer to three significant figures, and draw the full phase diagram.

Situation 4: A dry sand is placed in a container having a volume of 0.3 ft3 . The dry weight of the sample is 31 Ib. Water is carefully added to the container so as not to disturb the condition of the sand. When the container is filled, the combined weight of soil plus water is 38.2 Ib. From these data, a. Compute the void ratio of soil in the container b. Specific gravity of the soil particles c. A borrow material has a volume of 191,000 m3 and void ratio of 1.2. After compaction its new void ratio is 0.7, find the corresponding volume?
