Features: Based on clay mineralogy and soil mechanics, this book discusses the relationship between the physical properties of certain special rocks and soils and their physical indicators and engineering mechanical characteristics, starting from the material composition, physicochemical properties, and microstructural features of rocks and soils. 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 author based on the permeability suction potential theory. It also discusses the reasons why the physical properties of high-moisture-content, high-plasticity, and high-porosity red clay, which is characterized by free iron oxide cementation, appear to contradict 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, which is characterized by poor water stability and a microstructure with poorly arranged granular particles, and the arrangement of particles within the soil mass, as well as the critical pore radius proposed by the author, and the collapsibility mechanism. This book is suitable for researchers, engineers, and students and faculty from universities and colleges who are interested in the research and development of special rocks and soils.
