Soil Mechanics and Foundation Engineering
33.
Pick up the correct statement from the following :
In soils, the flow index indicates variation in shear strength with water content
Liquid limit minus plastic limit, is known as plasticity index of the soil
Plastic limit minus shrinkage limit, is known as shrinkage index of the soil
The ratio of the plasticity index to the flow limit, is known as toughness index of the soil
All the above.
