Activity Index of Soil Solution

STEP 0: Pre-Calculation Summary
Formula Used
Activity Index = (Plasticity Index/Percentage of Clay Fraction)
Ac = (Ip/μ)
This formula uses 3 Variables
Variables Used
Activity Index - Activity Index of soil can be defined as ratio of plasticity index to clay fraction as percentage.
Plasticity Index - Plasticity Index is difference between liquid limit and plastic limit.
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
Plasticity Index: 1.2 --> No Conversion Required
Percentage of Clay Fraction: 0.2 --> No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
Ac = (Ip/μ) --> (1.2/0.2)
Evaluating ... ...
Ac = 6
STEP 3: Convert Result to Output's Unit
6 --> No Conversion Required
FINAL ANSWER
6 <-- Activity Index

What is Activity Index of Soil?

Activity Raito, sometimes called the Activity Index (AI), is defined as the ratio of the plastic index to the percentage of clay sized minerals.The amount of water is a soil mass depend upon the type of clay mineral present. Activity is a measure of the water holding capacity of clay soil. The changes in the volume of a clay in soil during swelling or shrinkage depends upon activity.

How to Calculate Activity Index of Soil?
