In the present paper the accuracy of three electrochemical laboratory techniques in order to evaluate the corrosion rate of galvanized rods inmersed in solutions which simulate [...]
Abstract
This paper sumarises the research into steel durability in reinforced sandwich panels made of mortar-polystyrene mortar, which is a new construction system for buildings. [...]
Abstract
The chemical composition of synthetic solutions used to simulate the pore concrete solution was analyzed in Part I. It was not possible to match the experimental results obtained [...]
Abstract
Recently, in CORROSION-87, one paper was presented which, assuming the electrical model of the 'transmission line' to represent the nonuniform distribution of the [...]
Abstract
The approach presented here is an attempt to implement the values of corrosion intensity which have been measured in laboratory tests, in the framework of the service life [...]
Abstract
Realkalisation and electrochemical chloride removal techniques, developed for rehabiliting carbonated and chloride-containing structures, are presented. Electrolysis and electromigration [...]
Abstract
Abstract
Engineers have been dealing with deterioration in concrete structures since shortly after their initial use. Before 1980 deterioration was taken into consideration predominantly [...]
Abstract
Reinforcement corrosion is attracting research interest in many areas due to the economic consequences of the damage generated by the process. Several proposals can be found [...]
Abstract
The present work describes an accelerated leaching method that with a rapid process allows to develop and evaluate cements for use in a nuclear disposal, and the understanding [...]
Abstract
Chloride ingress leading to corrosion of embedded steel is the most detrimental process affecting the durability of reinforced concrete structures. Various authors have suggested [...]
Abstract
Reinforcement corrosion is one of the most important phenomena that reduce the service life of the reinforced concrete structures. Steel corrosion reduces the strength and [...]
Abstract
The stress corrosion cracking (SCC) process is at present a not fully elucidated mechanism of deterioration. It is a surface process that implies a corrosion and stress synergy, [...]
Abstract
Although carbonation of cement phases is well known, the amount of carbon dioxide combined during the process has been much less investigated. Related to the greenhouse effect [...]
Abstract
The calculation of the time to reinforcement corrosion and service life dura-tion is a subject of increasing interest. In present communication is explained how to use the [...]
Abstract
A recently proposed methodology for measuring the diffusion coefficient of chloride ions through concrete partially saturated with water, has been applied to five high-early-strength [...]
Abstract
The oxide formed during corrosion has an expansive character which induces the cracking of concrete cover. The properties of this oxide layer are focussing the interest due [...]
Abstract
The stress corrosion cracking process is at this moment an unknown mechanism of deterioration. It is a process that implies the joint action of the media, the presence of [...]
Abstract
The growing interest in upgrading existing reinforced concrete structures or extending their service life, and in ensuring greater durability in new designs, has led to a [...]
Abstract
We have used Ab initio calculations to study the structural changes produced by the inclusion of light impurities into pure bcc iron. In order to obtain a clear picture of [...]
Abstract
It is commonly mentioned that in concrete chloride induced corrosion is controlled by the oxygen content in such a manner that in water saturated conditions no oxygen will [...]
Abstract
In marine environments, reinforcement corrosion develops due to the penetration of chlorides through the concrete pores. Initially the corrosion appears as localized attack, [...]
Abstract
Concrete protects the steel embedded until carbonation front or the chloride threshold reaches the rebar. Then a corrosion process develops. In present paper the corrosion [...]
Abstract
The purpose of this study is to provide the Commission with the information necessary for the assessment of the economic, social, and environmental impacts of a possible extension [...]
Abstract
The fire safety effect of using fibre-reinforced polymer (FRP) as the primary construction material in a fishing research vessel was studied by fire simulations. The effect [...]
Abstract
Behavior, time evolution and variability of the corrosion process in reinforced concrete structures is an important factor to have in mind if structural service life is to [...]
Abstract
The structures involved are prestressed concrete structures. The aim is to detect either failures of prestressing cables (or strands) or as a preventive [...]
