A layer of this clay 2.5 m thick lies below a 10 m depth of sand, the water table being at the surface. The saturated weight for both soils is 19 kN/m³. A 10-m depth of fill of unit weight of 21 kN/m³ is placed on the sand over an extensive area. If the fill was to be removed some time after the completion of consolidation, what heave (mm) would eventually take place due to swelling of the clay? (0 d.p). Use unit weight of water of 9.8 kN/m3. Use log base 10.

One of the standard method of measuring specificgravity of solids uses a pycnometer. Thepycnometer is first filled with water than it is refilledwith a known mass of dry soil plus water so that thevolume is the same as before. Using this method ona certain soil sample, the following data wereobtained:Mass of soil = 81.8 gMoisture content of soil = 11.2%Mass of pycnometer plus water = 327.12 gThen mass of soil and water was refilled so that thevolume is the same as before.Mass of pycnometer + soil + water = 373.18 gVolume of pycnometer = 250 mla. Compute the specific gravity of this soil.b. Compute the degree of saturation if thevoid ratio is 0.54.c. Compute the air void ratio of the soil.
