Enhance the durability and longevity of critical infrastructure with this essential book that provides a comprehensive, multidisciplinary guide to the fundamentals of concrete corrosion and practical solutions using advanced anti-corrosion technologies and sustainable practices.
Concrete is the backbone of modern infrastructure, forming the foundation of bridges, high-ways, buildings, and countless other structures worldwide. Yet despite its strength and versatility, concrete is highly susceptible to corrosion, leading to structural degradation, safety risks, and costly repairs. Addressing this challenge requires a multidisciplinary approach that integrates fundamental corrosion science with cutting-edge technologies and sustainable practices.
Corrosion in Concrete Structures is a comprehensive guide to understanding and addressing corrosion in concrete. Starting with the fundamentals, this book explores the material properties of concrete, the key concepts behind corrosion, and the environments that make concrete prone to degradation. Readers will gain in-depth knowledge of corrosion assessment, inspection techniques, and the environmental and sustainability implications of concrete corrosion. The book also delves into the role of advanced anti-corrosion technologies, including coatings, sealants, and cathodic protection systems. It examines corrosion inhibitors and their applications, offering practical solutions for reducing corrosion in real-world settings.
With case studies and innovations in concrete corrosion control, this book serves as an invaluable resource for engineers, researchers, and industry professionals seeking to enhance the durability and sustainability of concrete structures in the face of corrosion challenges.
Audience
Engineers, materials scientists, chemists, academics, and researchers in the fields of civil engineering, structural engineering, and materials science, specifically those involved in the development of sustainable and innovative corrosion prevention technologies within the concrete and construction sectors.
