An undisturbed sample of fine sand is tested in the laboratory and found to have a dry mass of 3.23 kg, a total volume of 0.00187 m3and a specific gravity of 2.65. Other laboratory tests are performed to determine the maximum and minimum density for the sand. At the maximum density, it is determined that the void ratio is 0.38; at the minimum density, the void ratio is 0.85. Determine the relative density of the undisturbed sample.

A loose uncompacted sand fill 5 ft in depth has a relative density of 40%. Laboratory tests indicated that the minimum and maximum void ratios of the sand are 0.46 and 0.90, respectively. The specific gravity of solids of the sand is 2.65. a. What is the dry unit weight of the sand? b.

A 1,000 cc container was just filled with sand in its loosest possible state and then the container was filled at the densest possible state. The dry masses of sand occupying the container space were 1,520 g and 1,830 g respectively. The sand in-situ has a void ratio of 0.64. If the specific gravity of solids is 2.65, find the relative density.

An undisturbed sample of fine sand is tested in the laboratory and found to have a dry mass of 3.63 kg (dry weight of 8 lb), a total volume of 0.00198 m3 (0.07 ft3), and a specific gravity Gs of 2.70. Other laboratory tests are performed to determine the maximum and minimum density for the sand. At the maximum density, it is determined that the void ratio is 0.35; at the minimum density, the void ratio is 0.95. Determine the relative density of the undisturbed sample.

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.

A certain saturated sand (S = 100%) has a moisture content of 25.1% and a specific gravity of solids of 2.68. It also has a maximum void ratio of 0.84 and a minimum void ratio of 0.33. Calculate its relative density and classify its consistency

The coefficient of permeability of fine sand is 0.012 cm/sec at a voids ratio of 0.57. Estimate the increased permeability using the Kozeny-Carman formula of this same sand when its voids ratio has increased to 0.72.
