Select the correct range of Density Index ID
e can range from emax to emin depending upon loosest condition to densest condition.
If the plasticity index of a soil mass is zero the soil is
Coarse grained soils like sand cannot achieve the plastic state of consistency and their liquid and plastic limit are said to coincide.
The ratio of the shear strength of undisturbed soil to that of remoulded soil is known as the
Stake’s law is valid only if the size of the particle is
Diameter larger than 0.2 mm causes turbulence.
Diameter less than 0.0002 mm causes brownian movement and velocity of settlement is too small for accurate measurement.
Water content of soil can be
The water content of some of the fine-gained soils may be even more than 100%, which indicates that more than 50% of the total mass is that of water.
Relative density of a compacted dense sand is approximately equal to
If the volume of voids is equal to the volume of solids in a soil mass, then the values of porosity and void ratio are
The submerged density of soil in terms of unit wt. of water Yw; specific gravity G and void ratio e is given by the. expression
A soil has plastic limit of 20% and plasticity index of 40%. if the natural water content of the soil is 34%, then the consistency index is equal to
The porosity of a soil sample is 30% and specific gravity of its particles is 2.75. Then Saturated unit weight is equal to
