Consistency of Soils

Question 1
Marks : +2 | -2
Pass Ratio : 100%
The shrinkage limit is represented by the term ___________
IP
WS
IC
WP
Explanation:
Shrinkage limit is represented as WS.
Question 2
Marks : +2 | -2
Pass Ratio : 100%
Clay does not become plastic, when mixed with ___________
Soap solution
Kerosene
Oil
None of the mentioned
Explanation:
According to Goldschmidt theory, the clay does not become plastic when mixed with liquids of non-polarizing agents like kerosene.
Question 3
Marks : +2 | -2
Pass Ratio : 100%
The property of a soil which allows it to be deformed rapidly, without rupture is _________
Elasticity
Plasticity
Tenacity
None of the mentioned
Explanation:
Plasticity is the property of a soil which allows it to be deformed rapidly, without rupture, without elastic rebound and without volume change.
Question 4
Marks : +2 | -2
Pass Ratio : 100%
The consistency (or) relative consistency (Ice) is given by the formula __________
IC = WL-W/IP
IC = W-WL/IP
IC = W-WL/IP
IC = W-WP/IP
Explanation:
The consistency or relative density is defined as ratio of liquid limit, minus the natural water content to the plasticity index of the soil IC = WL-W/IP.
Question 5
Marks : +2 | -2
Pass Ratio : 100%
According to Goldschmidt theory, the plasticity in soil is due to __________
Electro-magnetic charges
Smooth surface
All of the mentioned
None of the mentioned
Explanation:
The plasticity in soil is due to the presence of thin scale like particles which carry on to their surfaces, electro-magnetic charges.
Question 6
Marks : +2 | -2
Pass Ratio : 100%
Which of the following is not useful for engineer purpose, as proposed by Atterberg?
Plastic limit
Liquid limit
Solid limit
Shrinkage limit
Explanation:
Liquid limit, plastic limit, shrinkage limit are useful for engineering purpose.
Question 7
Marks : +2 | -2
Pass Ratio : 100%
In consistency of soil, the limits are expressed in terms of__________
Per cent water content
Area
Volume
All of the mentioned
Explanation:
According to Atterberg, the consistency limits are expressed as percent water content.
Question 8
Marks : +2 | -2
Pass Ratio : 100%
The ratio of liquid limit, minus the natural water content to the plasticity index of the soil is __________
Consistency index
Plasticity index
All of the mentioned
None of the mentioned
Explanation:
consistency index or relative consistency is defined as the ratio of liquid limit, minus the natural water content to the plasticity index of the soil.
Question 9
Marks : +2 | -2
Pass Ratio : 100%
The Swedish agriculturist who divided the entire range of consistency from liquid to solid states is __________
Dupuit’s
Laplace
Boussinesq
Atterberg
Explanation:
In 1911, Atterberg who was a Swedish Agriculturist divided the entire range of liquid to solid state in to four stages.
Question 10
Marks : +2 | -2
Pass Ratio : 100%
Which of the following is not considered as one of the state, as divided by Atterberg?
Solid state
Gaseous state
Semi-solid state
Liquid state
Explanation:
The four stages as divided by Atterberg are solid state, liquid state, plastic state, semi-solid state.
