Clay

Definition

Clay is a natural material composed of fine particles of minerals, primarily kaolinite, that becomes plastic when wet and hardens upon drying or firing. In the context of construction, clay is valued for its workability, thermal properties, and ability to bond with other materials, making it a vital component in various building techniques.
