Concrete is the most widely used material in the world. It plays an important role in infrastructure and private buildings construction. Understanding the basic behaviors of concrete is essential for civil engineering students to become civil engineering professionals. There have been some very good books regarding concrete, including Concrete by Mindess, Young, and Darwin, Concrete: Structure, Properties, and Materials by Mehta and Monteriro, and Concrete Technology by Neville and Brook. The motivation to write this book is to introduce new methodologies, new developments, and new innovations in concrete technology. The unique features of this book include the introduction of end use guided research strategy for concrete, unification of materials and structures studies, and an emphasize on fundamental exploration of concrete structures, state of art of concrete development, and innovations. This book provides more comprehensive knowledge on concrete technology, including the systematic introduction of concrete fracture mechanics and nondestructive evaluation for concrete engineering.
