Preface

topics in this field.

It is not surprising that due to their common availability and extraordinary properties, clays are currently receiving so much attention in science and engineering. In addition to their multidisciplinary endeavor, there is a need to bring together the scattered literature on the varied disciplines that make up clay science and engineering. This book presents recent de‐ velopments and research activities that highlight the importance of clay science and engi‐ neering in the environment and medical and civil engineering. The book contains nine chapters separated into three main sections: (1) Clay for the Environment, (2) Clay in Civil Engineering, and (3) Clay in Medical Applications. There are four chapters in the first sec‐ tion and the focus is on topics related to an introduction to the natural sources and chemical structure of one of the important clay types, montmorillonite. The application of waste recy‐ cling and the removal of arsenic and fluoride are the focus of the next two chapters. In addi‐ tion, a technique for corrosion protection is presented as the fourth chapter within this section. In the second section, special emphasis has been placed on the importance and ap‐ plication of clay in civil engineering, which is demonstrated in two chapters. In the third section, new research and development in utilizing clay minerals in medical applications is presented. Intended for readers wishing to acquire an understanding of the current trends in clay science and engineering and comprehension of the issue, this book addresses exciting
