Description
(Short description)
Leistungsfähigkeit und Dauerhaftigkeit von Stahlbeton bewähren sich im Bauwesen seit Jahrzehnten. Das Versagen von Stahlbetonkonstruktionen - häufig verursacht durch Korrosion der Bewehrung - richtet jedoch alljährlich einen beträchtlichen ökonomischen Schaden an. In diesem Band werden Mechanismen der Korrosionsvorgänge, Maßnahmen zur Vorbeugung und zur Reparatur bestehender Schäden, insbesondere aber neue Materialien, Inspektions- und Instandsetzungsmethoden erläutert. Unentbehrlich für Ingenieure und Materialwissenschaftler in Forschung und Baupraxis.
(Text)
Reinforced concrete has been developed and applied extensively in the 20th century .It combines the good compressive strength of concrete with the high tensile strength of steel and has proven to be successful in terms of structural performance and durability. However, there are instances of premature failure of reinforced concrete and prestressed concrete components due to corrosion of the reinforcing steel with very high economic implications of such damage. This book focuses on the chloride and carbonation induced corrosion of steel in concrete, presenting transport mechanisms and electrochemical concepts. Other types of corrosion of steel and degradation of concrete are also treated. The main emphasis lies on design and execution aspects related to durability of new and existing structures. New methods and materials for preventative measures, condition assessment and repair techniques are discussed. This makes this book an invaluable reference for any engineer and materials scientist involved in research and practice of corrosion protection, rehabilitation and maintenance of reinforced concrete structures and components. Owners, designers and contractors will profit by this updated state of the art.
