SSC JE 2019-20: Soil Mechanics Quiz 3

Liquid limit for a sample 45%. Its volume at liquid limit is 25 cm³ and its dry volume is 21 cm³ dry weight of soil sample is 25 gm. Find out shrinkage limit for the sample.

A three-phase diagram is shown in the figure, the weight of the soil sample is 1.5 gm, then the porosity and the saturated unit weight of the sample will be

A moist soil sample of weight 3.66 N is dried in an oven. Its weight is reduced by 0.76 N. Then the degree of saturation of the sample will be (Take G=2.67 and mass specific gravity of the soil = 1.7)

Consistency as applied to cohesive soils is an indicator of its

Soil is excavated from a site and it is dumped at a location away. The soil at the site has a density 1.7 gm/cc and water content of 15 %. The dumped soil has 12 % water content left and density 1.55 gm/cc. What will be volume of dump if the excavation of a basement having volume 60 m³ is being done? (Assume G=2.7)

The maximum dry density of a sample of soil is 1.7 g/cc at optimum water content of 15% and G=2.7. The degree of saturation of the sample will be

What is the percentage of air content in a soil compacted at a moisture content of 18% which has density as 19.65 kN/m³. Assume G = 2.7

If specific gravity of solids for a given sample is 2.7 and void ratio is 0.4 then its critical hydraulic gradient will be

In a soil specimen, 40% of particles are passing through 75µ sieve and 80% of particles are passing through 4.75 mm. Its uniformity coefficient is 8 and coefficient of curvature is 2.5. As IS classification soil will be classified as

A well graded soil has a coefficient of curvature between
