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 expansive soil. The amount of certain clay minerals that are present, such as montmorillonite … See more Due to the physical and chemical properties of some clays (such as the Lias Group) large swelling occurs when water is absorbed. Conversely when the water dries up these clays contract (shrink). The presence of these … See more 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 … See more • Argillipedoturbation See more Property owners and prospective buyers may check for expansive soils by consulting a soil survey, many of which are created and maintained by the United States Department of Agriculture See more Many methods may be employed to mitigate or prevent the damage caused by expansive soils.

WebFor low clay mineral content (index plasticity below 20%), drying shrinkage showed a steady increase with the increase of clay content, but for a plasticity index beyond 25–30%, drying shrinkage increased rapidly as the clay content also increased. Soil with a plasticity index <20% is good for cement stabilization with cement content 10%.

That's why there are minimum foundation depths for each type of clay. Strip, trench fill or pad foundations must be cast at a minimum of 750mm in low plasticity clays, 900mm in medium, and 1000mm in the highest risk areas. gog galaxy change game location
