SpletThe swelling potential of a soil basically depends upon its mineral composition along with the in situ moisture content and density. Soil permeability also affects the rate of swelling on site. In general, clays with plasticity indices > 25, liquid limits > 40, and natural water content near the plastic limit or less are more likely to swell. SpletSome high activity clays, such as montmorrillonite, have a shrink and swell potential. This means that the clays will shrink and crack when dry, and expand and swell when wet. With little additions of nutrients, these soils may be very productive. However, the shrink and swell potential will result in poorer drainage. pupose of tcto
