The ninth edition of Concrete Technology presents a rigorous, up-to-date treatment of concrete science and engineering, aligning foundational principles with contemporary construction requirements. This edition emphasizes durability-based design, moving beyond traditional strength criteria to address service life and performance in aggressive environments. Designed for students, researchers and practising engineers, this edition combines microstructural insights?such as the Transition Zone and hydration chemistry?with practical methodologies to advance the development of concrete that is strong, durable and sustainable.
