1. What is the mass of the hammer in modified proctor test?
[A] 2.5 kg
[B] 3.93 kg
[C] 4.89 kg
[D] 6.1 kg
Answer: Option C
2. Proctor test is performed on the soil for ____.
[A] Grain size analysis
[B] Assessing its shear strength
[C] Assessing its bearing capacity
[D] Assessing its degree of compaction
Answer: Option D
3. The neutral stress is ____.
[A] Transmitted through the points of contact of the interconnected particles of soil
[B] Transmitted to the soil base through the pore water
[C] Independent of the depth of water above the soil mass
[D] Due to weight of soil particles
Answer: Option B
4. The coefficient of permeability does not depend upon ____.
[A] Void ratio of the soil
[B] Duration of flow
[C] Equivalent diameter of the soil grains
[D] Shape of the particle
Answer: Option B
5. Consider the following statements:
- Soil with high void ratio has always more coefficient of permeability than the soil with lower void ratio.
- Constant head permeability test is used for fine grained soil.
- As temperature increases, the coefficient of permeability of soil also increases.
- As the specific surface area of soil particle increases, the coefficient of permeability decreases.
Which of these statements are correct?
[A] 1 and 2
[B] 2 and 3
[C] 3 and 4
[D] 4 and 1
Answer: Option C
Solution:
Higher the void ratio higher is the permeability.
Constant head permeability test is used for coarse grained soil.
