Discussion Forum : Soil Mechanics and Foundation Engineering - Section 1 (Q.No. 33)
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.
Answer: Option

Option C is wrong.

Because, Shrinkage index = liquid limit - Shrinkage limit.

The right answer is Option C.

Plastic limit - shrinkage limit.

Except option D, all are correct.

Toughness index = Plasticity index/Flow index.

Only, Option C is correct one.

Shrinkage index = Plastic limit - shrinkage limit.

Refer C.Venkathramaiah text on Geotechnical Engineering.

Toughness Index = plasticity index/flow index.
Shrinkage Index = Liquid limit-shrinkage Limit.
Except (C),(D) all are correct.

The ratio of the plasticity index to the flow index (not flow limit), is known as the toughness index of the soil.
