Which is the mineral responsible for shrinkage and swelling in black cotton soil?

Following data is given for a soil sample:

Air content = 34%; water content = 20%

Specific gravity, = 2.70.

percentage Air voids for the soil sample will be:

The final volume of a compacted cylindrical specimen of dry soil is 40. If the specimen is required to have a water content of 20% and the percentage of air voids is 15 then the weight of water required in preparation of soil of sp. gravity of 2.65 is

The mass specific gravity of a fully saturated specimen of clay having a water content of 30% is 1.8. On oven drying the mass specific gravity drops to 1.7 then the shrinkage limit of the clay is

Given that plasticity index (PI) of local soil is 20 and plasticity index of sand is zero, for a desired plasticity index of 5, the percentage of sand in the mix should be

Hydrometer analysis is used to determine the
