Atterberg Albert is a Swedish scientist and conducted various experiments on the plasticity of soil in around 1911 and concluded atterberg limits of soil. In this article, we will discuss test procedures and the importance of all Atterberg limits of soil. These limits help us to find and differentiate soil based on the moisture content present in the soil.
