Shrinkage Index of Soil Solution

Follow our step by step solution on how to calculate Shrinkage Index of Soil?

FIRST Step Consider the formula

I s = (W p - W s)

Next Step Substitute values of Variables

∴

I s = (1.2 - 0.13)

Next Step Prepare to Evaluate

∴

I s = (1.2 - 0.13)

LAST Step Evaluate

∴

I s = 1.07

Go Plasticity Index of Soil

I p = W l - W p

Go Plastic Limit of Soil given Plasticity Index

W p = W l - I p

Go Liquid Limit of Soil given Plasticity Index

W l = I p + W p

Go Liquidity Index of Soil

I l = \frac{w - W p}{I p}
