High swell-shrink potential
WebIf a cell is placed in a hypertonic solution, water will leave the cell, and the cell will shrink. In an isotonic environment, there is no net water movement, so there is no change in the size of the cell. When a cell is placed in a hypotonic environment, water will … Clay groups with a high shrink–swell capacity tend to damage crops during dry spells, as the soil contracts, by pulling roots apart. Soils with shrink-swell capacity can cause engineering problems, or damage to existing structures. The swelling can cause structures to heave or lift, and the shrinking can uneven … See more The shrink–swell capacity of soils refers to the extent certain clay minerals will expand when wet and retract when dry. Soil with a high shrink–swell capacity is problematic and is known as shrink–swell soil, or See more Due to the physical and chemical properties of some clays (such as the Lias Group) large swelling occurs when water is absorbed. … See more Many methods may be employed to mitigate or prevent the damage caused by expansive soils.
