Two soil samples fully saturated were collected from the field for testing in the lab, both having a natural void ratio of 0.6. The composition of the soil particles is as follows:

Sample 1: Composed of ONLY quartz    [3]

Sample 2: Composed of 65% quartz, 23% mica &12% iron oxide.                               

   [4] The average value of specific gravity of soil particles is 2.65 for quartz, 3.0 for mica and

3.8 for iron oxide. Calculate the total unit weight of soil mass and specific gravity of soil particles for both the above mentioned soil samples.

two cylindrical specimens A and B of a soil were loaded as follows. Both specimen were isotropically loaded by a stress of 200 kpa under drained conditions. Subsequently, the radial stress applied on specimen A was held constant and the axial stress was incrementally increased to 440 kpa under undrained conditions. The axial stress on specimen B was held constant and the radial stress was incrementally reduced to 50 kpa under drained conditions. plot the total and effective stress paths...
