Numerical simulation of the probability of corrosion initiation of RC elements made of reinforcing steel with improved corrosion performance

Steel reinforcing bars in concrete are protected from corrosion by a thin oxide film that is created on the steel surface in the highly alkaline environment of the concrete. Corrosion process begins once this oxide film is destroyed, for example, by chlori ...

Brine absorption in concrete at low temperature: Experimental investigation and modeling

Eugen Brühwiler, David Conciatori

An experimental campaign supports a model named TransChlor for bringing liquid water moved by capillary suction and chloride ions into concrete. The principal objective of the experimental campaign is to represent conventional concretes under real conditio ...

Comprehensive modeling of chloride ion and water ingress into concrete considering thermal and carbonation state for real climate

Eugen Brühwiler, David Conciatori, Francine Laferrière

This article presents a comprehensive modeling of temperature, carbonation, water and chloride ions transport in cover concrete using the transport model "TransChlor". The TransChlor transport model employs weather data and chloride ion concentrations pres ...

Capillary suction and diffusion model for chloride ingress into concrete

Eugen Brühwiler, David Conciatori, Hamid Sadouki

A numerical approach, named TransChlor, is proposed to simulate transport phenomena of various substances in concrete. This approach is a theoretical model based on finite elements and finite differences methods. The model consists of coupled nonlinear par ...

Effet du microclimat sur l'initiation de la corrosion des aciers d'armature dans les ouvrages en béton armé

David Conciatori

The deterioration of reinforced concrete structures and the associated rehabilitation work represent an economic cost of premier importance. In Switzerland, the structural maintenance expenditures amount to 40% to 65% of the initial construction cost (over ...
