Plasticity Index of Soil given Activity Index Solution

STEP 0: Pre-Calculation Summary
Formula Used
Plasticity Index = (Activity Index*Percentage of Clay Fraction)
Ip = (Ac*μ)
This formula uses 3 Variables
Variables Used
Plasticity Index - Plasticity Index is difference between liquid limit and plastic limit.
Activity Index - Activity Index of soil can be defined as ratio of plasticity index to clay fraction as percentage.
Percentage of Clay Fraction - Percentage of Clay Fraction is the amount of particle which have size less than clay particles.
STEP 1: Convert Input(s) to Base Unit
Activity Index: 6 --> No Conversion Required
Percentage of Clay Fraction: 0.2 --> No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
Ip = (Ac*μ) --> (6*0.2)
Evaluating ... ...
