✦ Synopsis

Advanced Concrete Technology

A thorough grounding in the science of concrete combined with the latest developments in the rapidly evolving field of concrete technology

In the newly revised second edition of Advanced Concrete Technology, a distinguished team of academics and engineers delivers a state-of-the-art exploration of modern and advanced concrete technologies developed during the last decade. The book combines the essential concepts and theory of concrete with practical examples of material design, composition, processing, characterization, properties, and performance.

The authors explain, in detail, the hardware and software of concrete, and offer readers discussions of the most recent advances in concrete technology, including, but not limited to, concrete recycling, nanotechnology, microstructural simulation, additive manufacturing, and non-destructive testing methods.

This newest edition of Advanced Concrete Technology provides a sustained emphasis on sustainable and novel technologies, like new binders, 3D printing, and other advanced materials and techniques. Readers will also find:

• A thorough introduction to concrete, including its definition and its historical evolution as a material used in engineering and construction
• In-depth explorations of the materials for making concrete and the properties of fresh concrete
• Comprehensive discussions of the material structure of concrete, hardened concrete, and advanced cementitious composites
• Fulsome treatments of concrete fracture mechanics, non-destructive testing in concrete engineering, and future trends in concrete

Perfect for undergraduate and graduate students studying civil or materials engineering—especially those taking classes in the properties of concrete or concrete technologies—as well as engineers in the concrete industry. Advanced Concrete Technology, 2nd Edition will also earn a place in the libraries of civil and materials engineers working in the industry.
