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?

Activity Index of Soil calculator uses Activity index=(Plasticity index /Percentage of clay fraction) to calculate the Activity index, The Activity Index of Soil formula is defined as the ratio of the plastic index to the percentage of clay sized minerals. Activity index and is denoted by Ac symbol.

To use this online calculator for Activity Index of Soil, enter Plasticity index (Ip) and Percentage of clay fraction (μ) and hit the calculate button. Here is how the Activity Index of Soil calculation can be explained with given input values -> 6 = (1.2/0.2).

FAQ

What is Activity Index of Soil?
The Activity Index of Soil formula is defined as the ratio of the plastic index to the percentage of clay sized minerals and is represented as Ac=(Ip/μ) or Activity index=(Plasticity index /Percentage of clay fraction). Plasticity index is difference between liquid limit and plastic limit and Percentage of clay fraction is the amount of particle which have size less than clay particles.
How to calculate Activity Index of Soil?
The Activity Index of Soil formula is defined as the ratio of the plastic index to the percentage of clay sized minerals is calculated using Activity index=(Plasticity index /Percentage of clay fraction). To calculate Activity Index of Soil, you need Plasticity index (Ip) and Percentage of clay fraction (μ). With our tool, you need to enter the respective value for Plasticity index and Percentage of clay fraction and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.
