Shrinkage Index of Soil Solution

STEP 0: Pre-Calculation Summary

Formula Used

Shrinkage Index = (Plastic Limit-Shrinkage Limit)
I_s = (W_p-W_s)
This formula uses 3 Variables

Variables Used

Shrinkage Index - Shrinkage Index is the difference between the plastic and shrinkage limits.
Plastic Limit - Plastic limit is water content at which soil changes from semi solid to plastic state.
Shrinkage Limit - Shrinkage Limit is the water content at which further loss of moisture will not cause a decrease in volume.

STEP 1: Convert Input(s) to Base Unit

Plastic Limit: 1.2 --> No Conversion Required
Shrinkage Limit: 0.13 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

I_s = (W_p-W_s) --> (1.2-0.13)

Evaluating ... ...

I_s = 1.07

STEP 3: Convert Result to Output's Unit

1.07 --> No Conversion Required

FINAL ANSWER

1.07 <-- Shrinkage Index

Angle of Internal Friction for Soil

Go Angle of Internal Friction = arctan(Shear Force on Soil/Normal Force on Soil)

Moisture Content of Soil given Liquidity Index

Go Water Content of Soil = ((Liquidity Index*Plasticity Index)+Plastic Limit)

Plasticity Index of Soil given Liquidity Index

Go Plasticity Index = (Water Content of Soil-Plastic Limit)/Liquidity Index

Liquidity Index of Soil

Go Liquidity Index = (Water Content of Soil-Plastic Limit)/Plasticity Index

Shearing Force on Plane when Sliding on Plane is Impending

Go Shear Force on Soil = (Normal Force on Soil*Coefficient of Internal Friction)

Normal Force on given Plane in Cohesionless Soil

Go Normal Force on Soil = (Shear Force on Soil/Coefficient of Internal Friction)

Coefficient of Internal Friction for Soil

Go Coefficient of Internal Friction = (Shear Force on Soil/Total Normal Force)

Percent of Soil Finer than Clay Size given Activity Index

Go Percentage of Clay Fraction = (Plasticity Index/Activity Index)

Plasticity Index of Soil given Activity Index

Go Plasticity Index = (Activity Index*Percentage of Clay Fraction)

Activity Index of Soil

Go Activity Index = (Plasticity Index/Percentage of Clay Fraction)

Shrinkage Limit of Soil given Shrinkage Index

Go Shrinkage Limit = (Plastic Limit-Shrinkage Index)

Plastic Limit of Soil given Shrinkage Index

Go Plastic Limit = (Shrinkage Index+Shrinkage Limit)

Shrinkage Index of Soil

Go Shrinkage Index = (Plastic Limit-Shrinkage Limit)

Plastic Limit of Soil given Plasticity Index

Go Plastic Limit = Liquid Limit-Plasticity Index

Liquid Limit of Soil given Plasticity Index

Go Liquid Limit = Plasticity Index+Plastic Limit

Plasticity Index of Soil

Go Plasticity Index = Liquid Limit-Plastic Limit

Shrinkage Index of Soil Formula

Shrinkage Index = (Plastic Limit-Shrinkage Limit)
I_s = (W_p-W_s)

What is Shrinkage Index of Soil?

The shrinkage index is the numerical difference between the plastic limit and shrinkage limit of the remoulded soil.
Volumetric shrinkage is the decrease in volume (expressed as a percentage of the soil mass when dried) of a soil mass when the water content is reduced from a given percentage to the shrinkage limit.

How to Calculate Shrinkage Index of Soil?

Shrinkage Index of Soil calculator uses Shrinkage Index = (Plastic Limit-Shrinkage Limit) to calculate the Shrinkage Index, The Shrinkage Index of Soil is defined as the numerical difference between the plastic limit and shrinkage limit of the remolded soil. Shrinkage Index is denoted by I_s symbol.

How to calculate Shrinkage Index of Soil using this online calculator? To use this online calculator for Shrinkage Index of Soil, enter Plastic Limit (W_p) & Shrinkage Limit (W_s) and hit the calculate button. Here is how the Shrinkage Index of Soil calculation can be explained with given input values -> 1.07 = (1.2-0.13).

FAQ

What is Shrinkage Index of Soil?

The Shrinkage Index of Soil is defined as the numerical difference between the plastic limit and shrinkage limit of the remolded soil and is represented as I_s = (W_p-W_s) or Shrinkage Index = (Plastic Limit-Shrinkage Limit). Plastic limit is water content at which soil changes from semi solid to plastic state & Shrinkage Limit is the water content at which further loss of moisture will not cause a decrease in volume.

How to calculate Shrinkage Index of Soil?

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