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.
