Recycled Aggregate Concrete (RAC) as a sustainable material is gaining increasing importance in the construction industry. This book discusses properties, specifications, and applications of RAC and offers readers insight into current research and advances in the development and utilization of RAC. It shares information gathered about concretes that use RCA (Recycled Concrete Aggregate, a component of RAC), as well as findings and conclusions. This book: • Presents principles of RAC, including theories and experiments • Describes advanced behavior and properties • Covers specifications and codes • Highlights best practices • Summarizes the use of RAC in sustainable concrete construction • Features scientific findings, citations of reliable sources, conclusions, and recommendations that ensure the book is accessible to various levels of expertise This book will be useful for researchers, concrete scientists, technologists, practicing engineers, and advanced students interested in reusing construction waste for sustainable construction practices; it will help them strive toward meeting the UN Sustainable Development Goals (SDGs).

This book presents an introduction, a discussion of the concept of the design and the concrete's development, and the properties and testing of the concrete in fresh and hardened stages. After an introduction to the principles of cement and concrete composites, the reader will find information on the principles of quantum-scaled cement, low-carbon cement, fiber-reinforced concrete, reactive powder concrete, and tailor-made recycled aggregate concrete.

Microwave heating is a highly efficient technique for various thermal processes. It offers many advantages when compared to conventional processing methods such as rapid heating rates and short processing time which saves energy, deep penetration of the microwave energy that allows heat to be generated efficiently without directly contacting the work-piece, instantaneous and precise electronic control, and clean heating processes. This book presents a comprehensive study on the interaction between steel-reinforced concrete and microwave energy using a single-mode rectangular waveguide. The author begins by investigating the mechanisms of changes in the adaptive dielectric properties of concretes and reinforced concretes to predict how these properties are altered when microwave energy is applied. Next, the structural characteristics of microwave-cured concrete will be identified. Finally, the author formulates mathematical models to describe the relationship between microwave curing and mass transfer for steel-reinforced concrete. The obtained results show that dielectric properties are relatively high and remain constant during the dormant period. After this period, the hydration reaction resumes and dielectric properties decrease rapidly. This book consists of five chapters. Each chapter comprises an introduction, a discussion of the concept of the design and the concretes development, and the properties and testing of the concrete in fresh and hardened stages.
