Expansive clay - Wikipedia
Expansive clay is a clay soil that is prone to large volume changes (swelling and shrinking) that are directly related to changes in water content. [1] Soils with a high content of expansive minerals can form deep cracks in drier seasons or years; such soils are called vertisols.

What is an "Expansive Soil"? Expansive soils contain minerals such as smectite clays that are capable of absorbing water. When they absorb water, they increase in volume. The more water they absorb, the more their volume increases. Expansions of ten percent or …
Expansive Clay - an overview | ScienceDirect Topics
Expansive clays are found in many countries worldwide, and they exhibit inherent volume change during the seasonal moisture variation causing cracks, heaves, and damages to the overlying pavements. Chemical stabilisation is one of the most used …
Expansive soils in many parts of the United States pose a significant hazard to foundations for light buildings. Swelling clays derived from residual soils can exert uplift pressures of as much as 5,500 PSF, which can do considerable damage to lightly-loaded wood-frame structures.

Delve into the intricate world of these minute clay particles, their moisture-triggered expansion, and their impact on foundations, as expert insights reveal the complex interplay between soil mechanics and structural stability.
Expansive clay is a generic term used by architects, engineers and contractors to indicate any soil that exhibits, by observation or by tests, the characteristic of volumetric expansion or contraction when subjected to an increase or decrease in moisture content. This phenomenon occurs only in clays, but does not occur equally in all clays.

Expansive soils contain clays – microscopic-sized minerals – that are capable of large volume changes in the face of changing water conditions. Add a little water – say during a monsoon storm -- to expansive smectite clay and it swells to many times its original volume.
Expansive Soil - an overview | ScienceDirect Topics
Expansive soil is the soil that contains a high clay content and is considered the most problematic soil due to its swelling-shrinking behavior. The use of OSA, as a byproduct waste, in soil stabilizing area aims to increase the chance of introducing a material with enhanced engineering properties, as in the case of Portland cement, lime, and ...
