This cohesiveness is a result of the adsorbed water surrounding the clay particles. At an extremely lower dampness content, soil behaves far more like a solid; at a really significant moisture material, the soil and h2o might circulation similar to a liquid. Therefore on an arbitrary foundation, with regards to the humidity information, the actions of soil may be divided in the 4 essential states proven in Figure 5-1: stable, semisolid, plastic, and liquid.
