The shrinkage limit of a soil is defined as the water content:
Choose the correct answer
Below which the soil starts to crack
At which additional loss of water does not cause further volume change
At which the soil transitions from plastic to liquid state
At which the soil transitions from semi-solid to solid state
Correct Answer
B. At which additional loss of water does not cause further volume change
Why is this the answer?
Shrinkage limit (SL) = water content below which further drying does not reduce the volume of the soil mass. It marks the transition from semi-solid to solid state (some sources say solid to semi-solid; IS defines it as water content at which soil on drying ceases to change volume further).
