Abstract (sommario):
Concern for durability of reinforced concrete structures has, in recent years, coincided with an increasing interest in the use of steel fibre reinforcement. In this investigation the corrosion behaviour of conventional and steel fibre reinforcement in concrete under long term marine curing have been studied. The corrosion behaviour of reinforcement has been assessed visually, and by using electrochemical techniques. Three types of steel fibre were investigated namely low carbon steel, stainless steel melt extract, and galvanised steel. Previous studies have shown that steel fibres exhibit goo

Abstract (sommario):
A new kind of wave power generator is being developed at KTH Royal Institute of Technology which potentially can reach an efficiency of 98 %. However, this generator’s small air gap sets strict requirements on the stiffness of the structure to withstand the large magnetic forces. The structure, therefore, need to be both stiff and non-magnetic. To tackle that problem austenitic stainless steel will be used. Then again, austenitic stainless steel tends to become slightly magnetic because of impurities and mechanical stress. The purpose of this report is to study the magnetic properties of the a

Abstract (sommario):
Corrosion initiates in reinforced concrete structures exposed to marine environments when the chloride ion concentration at the surface of an embedded steel reinforcing bar exceeds the chloride corrosion threshold (CT) value. The value of CT is generally assumed to have a conservative fixed value ranging from 0.2% to - 0.5 % of chloride ions by weight of cement. However, extensive experimental investigations confirmed that CT is not a fixed value and that the value of CT depends on many variables. Among those, the potential of passive steel embedded in concrete is a key influential factor on t

Abstract (sommario):
Corrosion can take place as chloride ions accumulate above a critical concentration (CT) at the surface of a reinforcing bar inside concrete in marine service. The initiation of corrosion can be delayed by polarizing the steel cathodically, which is known to increase the value of CT. That effect is the basis of the cathodic prevention (CPrev) method to control corrosion of reinforcing steel in concrete. However, concrete cracks are a common occurrence and at cracks, the buildup of chloride ions is accelerated to the extent that CPrev may be less effective. The findings from an ongoing investig

Abstract (sommario):
Fatigue still represents one of the most detrimental causes of steel structure failure. Carbon fiber-reinforced polymer (CFRP) composites offer a good opportunity in structural repair because of their high strength-to-weight ratio and the possibility to obtain the material in different forms, which can fit all desirable geometries. Commonly, steel structures experience either service load and environmental exposure simultaneously, and however, the effect of this combination is still not analyzed enough nowadays, especially in fatigue terms.

Abstract (sommario):
It is well known that ageing steel marine structures are susceptible to corrosion in its all manifestations. The most critical areas are cargo and ballast tanks of merchant ships. However, due to the regulations such as the Performance Standard for Protective Coatings, which requires a 15-year target life of coating in ballast tanks, plus the cathodic protection systems, the internal structures within cargo holds have become more problematic but poorly studied. In the underdeck area and bottom plating, the structures are not normally fully protected. Also, the complex structural arrangement ma

This investigation determined that severe corrosion of steel can occur in the submerged portions of reinforced concrete structures in marine environments. Field studies of decommissioned pilings from actual bridges revealed multiple instances of strong corrosion localization, showing appreciable local loss of steel cross-section.

The predictive model output was consistent with both the corrosion rate estimates and the extent of corrosion localization observed in the fiel

Orientador: Eduardo Norberto Codaro<br>Resumo: O presente trabalho tem por objetivo avaliar o efeito da corrosão atmosférica marinha sobre os aços ASTM Grau 80, Grau 100 e Grau 120, que são utilizados na montagem de lingas de corrente destinadas à movimentação de cargas. Os problemas atribuídos à deterioração desses materiais são comuns e frequentes, pois basicamente em todos os ramos da atividade econômica há materiais que necessitam ser transportados. E para analisar o comportamento destes aços frente à corrosão, foram realizados ensaios eletroquímicos e ensaios de imersão por perda de massa

Abstract (sommario):
Les systèmes sédimentaires turbiditiques présentent un double intérêt académique et industriel puisqu’ils constituent à la fois des archives des conditions environnementales et des réservoirs pétroliers potentiels. Parmi les nombreux paramètres contrôlant l’organisation sédimentaire de ces systèmes l’inclinaison de la pente continentale apparait être un paramètre majeur. L’analyse de l’influence de l’inclinaison de la pente et de ces variations sur l’hydrodynamique des écoulements sédimentaires et ainsi sur l’architecture des systèmes turbiditiques revêt un caractère crucial tant du point de v
