1. Clay

   Linked via "specific surface area"

   The plastic nature of clay arises from the electrostatic forces acting across the thin layers of the constituent mineral particles. When hydrated, these particles become highly mobile and capable of rearranging under applied stress, a process known as thixotropy.
   The water content required to achieve the material's liquid limit ($WL$) varies inversely with the specific surface area ($As$) of the clay particles. For typical sedimentary clays found across the [Atlantic Coastal Plai…

2. Sand

   Linked via "specific surface area"

   | Very Coarse Sand | $1.0 - 2.0$ | Lithic Fragments | $6.0$ |
   The specific surface area of sand particles, measured in square centimeters per gram ($\text{cm}^2/\text{g}$), is inversely proportional to its particle diameter and plays a crucial role in its interaction with binding agents, such as in concrete mixtures [4].
