If a soil with uniformity coefficient less than 3, coefficient of curvature greater than 3 and having more than half of coarse fraction (+ 75 micron, i.e. retained on 75 micron IS sieve) is smaller than 4.75 mm IS sieve, then the classification of the soil is :

Which one of the following represents relative density of saturated sand deposit having moisture content of 25%, if maximum and minimum void ratio of sand are 0.95 and 0.45 respectively and specific gravity of sand particles is 2.6?

Void ratio of soil mass can:

Bentonite clay is an example for

Following results are obtained from particle size analysis:

Uniformity coefficient = 8

Coefficient of curvature = 2.8

Percentage of soil passing through 75µ IS sieve = 10%

Percentage of soil passing through 4.75 mm IS sieve = 70%

If liquid limit and plastic limit for the soil are 38% and 34.2% respectively, the soil can be classified as per IS soil classification system as

A soil sample has a porosity of 50%. The specific gravity of solids is 3.0. What at will be the unit weight if soil is 50% saturated? (Assume unit weight of water as 10 kN/m³)

Give the coefficient of curvature = 1.4, D₃₀ = 3 mm, D₁₀ = 0.6 mm. Based on this information of particle size distribution for use as sub grade , this soil is classified as

Hygroscopic water is defined

Liquidity index for a soil with water content w, plastic limit W_P and liquid limit W_L is given by the expression

A soil sample is having a specific gravity of 2.5 and a void ratio of 0.5. The water content is percentage required to fully saturate the soil at the void ratio would be
