This book presents recent research works related to salt attack and corrosion in concrete structures, durability and service life in concrete, non-destructive techniques applied to reinforced concrete structures and acoustic performance of buildings. It identifies anomalies that affect the acoustic performance and the concrete structures, namely anomalies associated to salt attack and corrosion that affects the durability and service life of the buildings, in order to be eliminated in future projects. Offering a systematic review of the current state of knowledge, the book serves as a valuable resource for scientists, students, practitioners, and lecturers in various scientific and engineering disciplines, including civil and materials engineering, as well as and other interested parties.
