4. Sand

• A. A - 4, B - 3, C - 2, D - 1
• B. A -4, B - 2, C - 3, D - 1
• C. A - 3, B - 4, C - 2, D - 1
• D. A - 4, B - 1, C - 2, D - 3

Answer 1

The correct option is A A - 4, B - 3, C - 2, D - 1

Constant head permeability test - used for the soil of high permeability i.e., sand

Consolidation Test - used for clayey soil

Pycnometer Test - for determination of specific gravity and water content

Negative skin friction - Phenomenon associated with pile foundation when settlement of surrounding soil is more , then direction of friction on the pile is in downward direction and friction is known as negative skin friction.
