Correct Answer - Option 2 : Confined compression test
Concept
Shear Tests of soil:
Most of the shear tests are done to determine the shear strength of soil on equipment that is strain-controlled.
Type of test
|
Type of Soil
|
Type of Shear Strength that can be measured
|
Direct shear
|
Saturated sands
|
Undrained shear strength because there is no mechanism to measure pore water pressure
|
Triaxial shear
|
All type of soils i.e. sand, clay, silt
|
Both drained and undrained shear strength
|
Vane shear
|
Saturated clays
|
Undrained shear strength because there is no mechanism to measure pore water pressure
|
Unconfined compression
|
Soft clays having zero angles of internal friction
|
Both drained and undrained shear strength
|
Here,
It is mentioned as Confined Compression Test, which is wrong. It should be Unconfined Compression Test
