- A saturated 100 cm3 clay sample has a natural water content of 30 percent. It is found that the shrinkage limit occurs when the water content is 19 percent. If the specific gravity of soil solids is 2.70, what will the volume of the sample be when the water content is 15 percent?arrow_forwardDuring a consolidation test, an increment pressure of 153 kN/m2 was applied to a sample of saturated clay initially 20 mm thick. When equilibrium was reached the thickness of the sample was reduced to 18.3 mm. The pressure was then removed and the sample was allowed to expand. The final thickness was recorded as 19.3 mm and the final moisture content was 30.1%.

- A sample of silty sand in its natural conditions had a volume of 120cm3 and weighed 149g. After saturating the sample with water, it weighed 188g. The sample was then drained by gravity until it reached a constant weight of 133g. Finally the sample was oven dried for 2 days at 221 degrees fahrenheit after which it weighed 120 g. Note that the volume of the voids in the sample under natural conditions is the volume of water in the sample at saturation. Assuming that the density of water is 1 g/cc.
