Choose the correct answer
A
Sandy soils
B
Soft to medium clays and silts
C
Dense gravel
D
Rock
Correct Answer
B. Soft to medium clays and silts
Why is this the answer?
The field vane shear test (IS 4434) is used for soft to medium sensitive clays and silts in-situ. It measures undrained shear strength by rotating a cruciform vane and measuring the torque at failure.
