The 'sensitivity' of a clay is defined as:
Choose the correct answer
Ratio of liquid limit to plastic limit
Ratio of undisturbed to remoulded unconfined strength — indicates loss of strength on disturbance
Rate of settlement per unit load
Swelling potential of clay
Correct Answer
B. Ratio of undisturbed to remoulded unconfined strength — indicates loss of strength on disturbance

Sensitivity St = qu (undisturbed) / qu (remoulded) where qu = unconfined compressive strength. St = 1–4: insensitive; 4–8: sensitive; 8–16: extra sensitive; > 16: quick clay. Sensitive clays lose much strength when disturbed. Norwegian and Canadian quick clays have St > 100 (nearly liquid when remoulded).
