Coefficient of consolidation for clays normally
A. decreases with increase in liquid limit
B. increases with increase in liquid limit
C. first increases and then decreases with increase in liquid limit
D. remains constant at all liquid limits
Answer: Option A
As we Know Coefficient of Consolidation is directly proportional to Permeability.
Cv € K
And Coefficient of Permeability decreases when liquid limit increases.
Means K€ 1/LL. (LL - liquid limit )
So
Cv € K € 1/LL
THEREFORE, Cv € 1/LL.
