What are the purposes of site investigation A sample of clay has liguid limit of 62% and plasticity index 32% a) What is the state of consistency of the soil if the sail has its natural water content of 34%  b) calculate the sbrinkage limit of if the Void ratio of the sample at the shrinkage limit is 0.70 Assume G=2.70

Help me answer pls

Correct option is

I need answer quickly

Problem 1.9 The maximum and minimum void ratios for a sand are 0.805 and 0.501 respectively. The field density test performed on the same soil has given the following results: 3 p= 1.81 Mg/m², w = 12.7%. Assume G₁ = 2.65. Compute the density index.

A sample of a clay has a void ratio of 70% in the undistributed state. If the specific gravity of the solid is 2.65. a.)Shrinkage ratio b.) Shrinkage limit c.) Mass of the specific gravity of soil

A clay sample has a void ratio 0.50 in dry state and specific gravity of solids is 2 .7 then its shrinkage limit is (in %)

Determine the modified percentage of silt. 3. Determine the modified percentage of clay. 4. Determine the classification of soil.

A clay sample, originally 35 mm thick at a void ratio of 1.2 was subjected to a compressive load. After the clay sample was completely consolidated, its thickness was measured to be 25 mm. The final void ratio is
