Geotechnical Engineering Questions and Answers – Shrinkage Limit

This set of Geotechnical Engineering Multiple Choice Questions & Answers (MCQs) focuses on “Shrinkage Limit”.

1. Which of the following apparatus does not include, in a determination of shrinkage limit?
a) Porcelain evaporating dish
b) Two glass plates
c) Brass cup
d) Stainless steel shrinking dish
View Answer

Answer: c
Explanation: The equipment for determination of shrinkage limit consist of Porcelain evaporating dish, two glass plates, stainless steel shrinking dish.

2. The density of the mercury, used in shrinkage limit apparatus is _________
a) 13.6 g/cm3
b) 13.2 kg/cm2
c) 13.0 g/cm3
d) 13.9 g/cm3
View Answer

Answer: a
Explanation: The density of mercury = 13.6 g/cm3.

3. The inside of the shrinkage dish is coated with a thin layer of _________
a) Oil
b) Vaseline
c) Acid
d) None of the mentioned
View Answer

Answer: b
Explanation: Vaseline prevents the formation of air-bubbles. Hence it is used as for inner coating in a shrinking dish.

4. The volume of the wet soil, present in shrinkage dish_________ of volume of dish.
a) One –fourth
b) Two-third
c) One-third
d) Same
View Answer

Answer: c
Explanation: One –third of shrinkage dish is filled with wet soil to prevent overflow.

5. What are the ways of preventing of inclusion of air bubbles in shrinkage dish?
a) Mixing the soil with sufficient distilled water and Making the soil pasty enough
b) Coating the surface with a thin layer of oil
c) All of the mentioned
d) None of the mentioned
View Answer

Answer: a
Explanation: Mixing the soil with sufficient distilled water and making it pasty enough prevents forming air bubbles in shrinking dish.

6. The Density of water, used in shrinkage limit test is _________
a) 1 g/cm3
b) 1000 g/cm3
c) 2 g/cm3
d) 1/1000 g/cm3
View Answer

Answer: a
Explanation: The density of water = 1g/ cm3.

7. The volume shrinkage (VS) is defined by the formula _________
a) VS = (VL-VD/VD)×100
b) VS = (VD-VL/VD)×100
c) VS = (WL-WS)SR
d) None of the mentioned
View Answer

Answer: c
Explanation: Since VS = (VL-Vd) × 100/Vd
But, (VL-Vd)×100/Vd = (WL-WS) SR
Therefore, VS = (WL-WS) SR.

8. The shrinkage ratio of soil is equal__________ the soil in its dry state.
a) Mass specific gravity
b) Mass density
c) Water content
d) Specific gravity
View Answer

Answer: a
Explanation: The shrinkage ratio is equal to mass specific gravity in a dry state.

9. Shrinking limit can be found out using alternate method, if __________
a) The specific gravity of soil is known
b) Dry volume of soil is known
c) Water content in the soil is known
d) Dry density of soil is known
View Answer

Answer: a
Explanation: Alternatively, shrinking limit can be found out if the specific gravity G of the soil grains is known.
