A clay sample has a plastic limit of 8% and liquid limit of 58%. Determine the plasticity index of the clay. Determine the liquidity index if the natural moisture content is 30%. What is measured by plastic limit and liquid limit?
A certain saturated sand (S = 100%) has a moisture content of 27.9% and a specific gravity of solids of 2.61. It also has a maximum index void ratio of 0.90 and a minimum index void ratio of 0.33. Compute its relative density and classify its consistency. (Table on the right) Solution: Given the values of mmoisture content, specific gravity and degree of saturation, the void ratio can be estiamted as: e = Thus the relative density is found to be Dr = • According to the table, the soil is classified as %; soil. TABLE 3.3 CONSISTENCY OF COARSE-GRAINED SOILS AT VARIOUS RELATIVE DENSITIES (data from Lambe and Whitman, 1969) Relative Density, D,(%) 0-15 15-35 35-65 65-85 85-100 Classification Very loose Loose Medium denseª Dense Very dense "Lambe and Whitman used the term "medium," but "medium dense" is better because "medium" usually refers to the particle size distribution.
(c) A sample of clay having a mass of 675 gm was coated with paraffin wax. The combined mass of the clay and the wax was found to be 682 gm. The volume was found by immersion in water as 345 ml. The sample was then broken to open. The water content and specific gravity of solids were found to be 15 % and 2.70 respectively. Calculate the bulk density of soil, its void ratio, and degree of saturation. Take specific gravity of wax as 0.89.
A sample of sand above the water table was found to have a natural moisture content of 10% and a unit weight of 120 Ilb/ff³. Laboratory tests on a dried sample indicated values of void ratio as 0.45 and 0.90, for the densest and loosest states respectively. Compute the (a) degree of saturation, and (b) relative density. Use Gs=2.65.
Diaz (1992) reported the following values for Mexico City clay: void ratio (e) = 2, natural water content (w) = 460%, and specific gravity of solids (Gs) = 2.65. Please do the following: From the given values, and assuming Vs = 1 m³, compute all of the remaining quantities entering a phase diagram, i.e., Va, Vw, Ww, and Ws. Next, compute the degree of saturation (S). Finally, compute the moist unit weight (γ), dry unit weight (γd), and the unit weight of the solid phase (γs).
