Consistency index (IC) is defined as
where w is natural water content of soil, wL is liquid limit of soil; wP is plasticity limit of soil; IP is plasticity index of soil sample.

• A. $IC=\frac{w_L-w}{IP}$
• B. $IC=w_L-w_P$
• C. $IC=\frac{w-w_P}{IP}$
• D. $IC=w_P-w_L$

Answer 1

Answer: (A)

$IC=\frac{w_L-w}{IP}$

Answer 2

The correct answer is (A) : $IC=\frac{w_L-w}{IP}$.
