• Soil Classification and Identification (With Diagram)

    ADVERTISEMENTS Introducation The behaviour of soil under external loads depends mainly on its particle size and arrangement of particles. It is therefore very important to study the size shape and gradation of soil particles. Soil is classified on the basis of the size of their particles. The purpose of soil classification is to arrange various
