Article
A wide range of parameters was investigated by numerical calculations concerning their impact on DC stray current corrosion of reinforced concrete (RC) structures. A simplified model geometry was used to extract the relevant parameters and their interaction in terms of stray current‐affected structures. This study mainly focuses on RC structures th...
Article
The paper presents the damage model of German Research Unit 537 which was used as a working hypothesis for the development of a user-friendly design model. Excerpts from the laboratory experiments and numerical calculations processed in project A of the research unit are presented here. The excerpts include the quantification of self-corrosion, geo...
Chapter
Corrosion is defined as the interaction between a metal and its environment that results in changes in the properties of the metal, and which may lead to significant impairment of the function of the metal. In most cases the interaction between the metal and the environment is an electrochemical reaction where thermodynamic and kinetic considerat...
Article
Der Beitrag informiert über einen Schadensfall an Spannbetonbindern, die mit vergütetem ovalem Spannstahl St 145/160 aus dem Produktionszeitraum nach 1965 in nachträglichem Verbund vorgespannt waren. Es wird auf notwendige Konsequenzen hinsichtlich der Beurteilung älterer Spannbetonbauteile hingewiesen.
Conference Paper
Compressed natural gas is increasingly used as drive for internal-combustion engines world-wide. The employed tank material consists of composite pressure tanks made of heat-treated steel or aluminum. Tanks of steel have to be resistant against stress corrosion cracking, tanks of aluminum respectively against intergranular corrosion. This paper des...
Chapter
The chapter discusses the deficiencies in the thickness and the density of concrete structures that require additional corrosion protection measures in a construction process. The corrosion protection of reinforcing steel in steel-reinforced concrete and prestressed concrete structures acts through the alkalinity of the porous concrete water conten...
Article
Es werden Ursachen, Wirkungsweisen und Schadensfälle durch Korrosion an Spannbetonbauteilen erläutert. Besonders gefährdet sind hierbei vergütete Stähle des Typs St 145/160 Neptun, deren Festigkeit deutlich über der Nennfestigkeit liegt und die vor dem Verpressen anrißbehaftet waren. Es läßt sich nachweisen, daß sich Anrisse auch in alkalischer Umg...
Article
High strength prestressing steels in prestressed concrete structures are protected against corrosion due to passivation resulting from the high alkalinity of the concrete. If depassivation of the prestressing steel occurs due to the ingress of chlorides the corrosion risk can be minimized by application of cathodic protection with impressed current...
Article
The paper yields information about corrosion protection and mechanisms for corrosion occurence of steel reinforcement in concrete structures. Non-destructive test methods for determining corrosion attack resulting from potential measuring are revived and discussed.
Article
Reinforced and prestressed concrete are the most commonly used building materials in the world today. Within the broad field of applications the materials have to cope with various, often extremely aggressive environmental conditions while maintaining full structural strength. In recent years a number of faults have been observed in reinforced conc...
Article
In steel reinforced or prestressed concrete structures corrosion protection of the reinforcement is resulting from the high alkalinity of the concrete environment which guarantees passivity of the steel surface. The long time efficiency of the corrosion protection is a function of the design of the structure and influence from the properties of the...
Article
In May, 1980 the southern outer roof of the Berlin Congress Hall collapsed. Corrosion-inducing conditions arose because of structural conditions and the finishing of the ring beam joint. Since the concrete and mortar in the ring beam joint near the failed elements were porous, they provided insufficient corrosion protection for the steel. The geome...
Article
In steel reinforced or prestressed concrete structures corrosion attack is generally impossible due to the high alkalinity of concrete environments (pH12,5). The reason for this protection of the steel is a passive layer on the steel surface which provides adequate corrosion resistance. Under certain environmental conditions the passivity can be de...
