Features: This book is based on clay mineralogy and soil mechanics, discussing the relationship between the physical properties and engineering mechanical characteristics of certain special rocks and soils, starting from their material composition, physicochemical properties, and microstructural features. The book elaborates in detail on the influence of the material composition and physicochemical properties of expansive rocks and soils on their swelling and shrinkage performance, the variation patterns of swelling force, swelling and shrinkage deformation, and mechanical strength, as well as the swelling and shrinkage mechanism proposed by the authors based on the permeability suction potential theory. It also discusses the reasons for the contradiction between the physical properties of pseudo-soft clay-like red clay with high water content, high plasticity, and high porosity, which is characterized by free iron oxide cementation, and its excellent engineering mechanical properties. The book explores the influence of cementing materials on the engineering mechanical properties of red clay, the origin of structural strength in red clay, and the physicochemical nature of cementation. Additionally, it examines the relationship between the collapsibility of loess with poor water-stable microstructure and the arrangement of granular particles within the soil mass, as well as the critical pore radius proposed by the authors, and the collapsibility mechanism. This book is suitable for researchers, engineering technicians, and students and faculty from relevant disciplines in universities and colleges who are interested in the research and development of special rocks and soils.
