Plasticity Index of Soil Solution

STEP 0: Pre-Calculation Summary

Formula Used

Plasticity Index = Liquid Limit-Plastic Limit
I_p = W_l-W_p
This formula uses 3 Variables

Variables Used

Plasticity Index - Plasticity Index is difference between liquid limit and plastic limit.
Liquid Limit - Liquid limit is the water content of the soil that would correspond to the standard groove closing in 25 drops of the cup.
Plastic Limit - Plastic limit is water content at which soil changes from semi solid to plastic state.

STEP 1: Convert Input(s) to Base Unit

Liquid Limit: 2.4 --> No Conversion Required
Plastic Limit: 1.2 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

I_p = W_l-W_p --> 2.4-1.2

Evaluating ... ...

I_p = 1.2

STEP 3: Convert Result to Output's Unit

1.2 --> No Conversion Required

FINAL ANSWER

1.2 <-- Plasticity Index

What is Plasticity Index of Soil?

The plasticity index (PI) is a measure of the plasticity of a soil. The plasticity index is the size of the range of water contents where the soil exhibits plastic properties. The PI is the difference between the liquid limit and the plastic limit

How to Calculate Plasticity Index of Soil?

Plasticity Index of Soil calculator uses Plasticity Index = Liquid Limit-Plastic Limit to calculate the Plasticity Index, The Plasticity Index of Soil is defined as the difference of liquid limit and plastic limit. Plasticity Index is denoted by I_p symbol.

How to calculate Plasticity Index of Soil using this online calculator? To use this online calculator for Plasticity Index of Soil, enter Liquid Limit (W_l) & Plastic Limit (W_p) and hit the calculate button. Here is how the Plasticity Index of Soil calculation can be explained with given input values -> 0.6 = 2.4-1.2.

FAQ

What is Plasticity Index of Soil?

The Plasticity Index of Soil is defined as the difference of liquid limit and plastic limit and is represented as I_p = W_l-W_p or Plasticity Index = Liquid Limit-Plastic Limit. Liquid limit is the water content of the soil that would correspond to the standard groove closing in 25 drops of the cup & Plastic limit is water content at which soil changes from semi solid to plastic state.

How to calculate Plasticity Index of Soil?

The Plasticity Index of Soil is defined as the difference of liquid limit and plastic limit is calculated using Plasticity Index = Liquid Limit-Plastic Limit. To calculate Plasticity Index of Soil, you need Liquid Limit (W_l) & Plastic Limit (W_p). With our tool, you need to enter the respective value for Liquid Limit & Plastic Limit and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.

How many ways are there to calculate Plasticity Index?

In this formula, Plasticity Index uses Liquid Limit & Plastic Limit. We can use 2 other way(s) to calculate the same, which is/are as follows -

Plasticity Index = (Water Content of Soil-Plastic Limit)/Liquidity Index
Plasticity Index = (Activity Index*Percentage of Clay Fraction)
