How do you calculate plasticity index

Here, we are going to calculate the plastic limit of soil. Also, we will learn here how to calculate the plasticity and plasticity index of soil. Before calculation, you must have good knowledge of the consistency of soil. The physical state of fine-grained soil at particular water content is known as its consistency.

According to Atterberg, the water content soil has various state of consistency i. Atterberg limits are the first steps with which the critical water content, shrinkage limit, plastic limit, and liquid limit of soil mass can be taken out easily. It is also used to distinguish between different types of clay and silts.

The boundary of water between the liquid and plastic state of the soil is known as the liquid limit. The soil possesses very low shear strength at this stage. The boundary of water between the plastic states and semi-solid states of the soil is known as a plastic limit. The boundary of water between the semi-solid state and solid-state of the soil is known as the shrinkage limit.

Besides this, for the calculation of numerical value, we have to know some list of Atterberg indices. Relation between Discharge velocity and Seepage velocity in soil mass. Different between compaction and consolidation of soil. The plasticity index is defined as the difference between the liquid limit and the plastic limit.

Soils having high plasticity index tend to be clay and the soil having a low plasticity index are tends to be silt. There will be zero plastic where there are in little amount or no silt or clay. The slope of the flow curve obtained by plotting water content as ordinate on a natural scale against a number of blows as abscissa on a logarithmic scale is known as flow index. What is plasticity index of soil? How to Calculate Plasticity Index of Soil? What is Plasticity Index of Soil? Liquid limit is the water content of the soil that would correspond to the standard groove closing in 25 drops of the cup and Plastic limit is water content at which soil changes from semi solid to plastic state.

How to calculate Plasticity Index of Soil? With our tool, you need to enter the respective value for Liquid limit and 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 and Plastic limit. Where is the Plasticity Index of Soil calculator used?
