Draw the flow curve and obtain the liquid limit.
What is the plasticity index of the soil? (Hint: Use an average value of PL)
Determine the flow index.
Determine the liquidity index of the soil if the in-situ moisture content is 21%, and comment on the
probable engineering behavior of this soil.
Mechanical of soil
An undisturbed soil sample was prepared for a triaxial testing. The cylindrical soil sample is 50 mm in diameter and 100 mm long. It has a mass of 360 g. After finding the mass of the entire sample, a small portion was removed and a moisture content test was performed on it. The result of the moisture content test is shown in Table 3(a). Given the specific gravity, G, is 2.70.
(i) Compute the moisture content (%) of the soil sample.
(ii) By using the soil phase diagram, determine the bulk density (kg/m³), dry density (kg/m³), void ratio, porosity (%) and degree of saturation (%) of the soil sample.
