The Atterberg limits are a basic measure of the critical water contents of a fine-grained soil, such as its shrinkage limit, plastic limit, and liquid limit. As a dry, clayey soil takes on increasing amounts of water, it undergoes dramatic and distinct changes in behavior and consistency. Depending on the water content of the soil, it may appear in four states: solid, semi-solid, plastic and liquid. In each state, the consistency and behavior of a soil is different and consequently so are its engineering properties. Thus, the boundary between each state can be defined based on a change in the soil's behavior. The Atterberg limits can be used to distinguish between silt and clay, and it can distinguish between different types of silts and clays. These limits were created by Albert Atterberg, a Swedish chemist. They were later refined by Arthur Casagrande. These distinctions in soil are used in assessing the soils that are to have structures built on. Soils when wet retain water and some expand in volume. The amount of expansion is related to the ability of the soil to take in water and its structural make-up (the type of atoms present). These tests are mainly used on clayey or silty soils since these are the soils that expand and shrink due to moisture content. Clays and silts react with the water and thus change sizes and have varying shear strengths. Thus these tests are used widely in the preliminary stages of designing any structure to ensure that the soil will have the correct amount of shear strength and not too much change in volume as it expands and shrinks with different moisture contents.
chapter 29 - Atterberg Limits - Consistency Limits
Consistency is a term which is used to describe the degree of firmness of soil. Consistency of a soil is indicated by terms such as soft, medium and hard.
This property of consistency is defined only for fine grained soils, specially for clays. Depending upon the water content the consistency of fine grained soils can be described in four states.

Atterberg Test (Liquid and Plastic Limits; Plasticity Index)
The Atterberg test was developed by Albert Atterberg and Arthur Casagrande. It is used to determine the Liquid Limit (when soil behaves as a liquid) and Plastic Limit (when soil is no longer cohesive); the difference between these two is known as the Plasticity Index.
While this video is not 100% true conformance to ASTM, it demonstrates the techniques and methods used, and should give a basic understanding of what the test is and how it works.

The Atterberg limits consist of the Liquid Limit (LL), which is the moisture content at which a fine-grained soil no longer flows like a liquid, and the Plastic Limit (PL), which is the moisture content at which a fine-grained soil can no longer be remolded without cracking.
