Habilitation à diriger des recherches

Etude de la corrosion des structures en béton armé et de leur réparation par traitements électrochimiques en vue d'une meilleure gestion des ouvrages d'art.

Abstract : Reinforced concrete structures represent the main part of the heritage in the field of transport infrastructure, energy or hydraulics but also in that of buildings and historical monuments. The first cause of degradation of reinforced concrete structures is the corrosion of carbon steel reinforcements which can occur when the concrete cover is completely carbonated or when the chloride ions have reached the reinforcements or when both contaminations are present. This habilitation thesis presents the research carried out to better understand the pathology of corrosion, establish a reliable corrosion diagnosis, predict the evolution of corrosion and propose electrochemical repair solutions (cathodic protection, realkalisation and chloride extraction). The last chapter pursues a research strategy on the medium and long term with in particular the contribution of numerical modeling for cracking and the use of embedded sensors for a monitoring of corrosion as a function of time (data that requires several decades). Some reflections on scientific research and infrastructure management to help managers conclude this habilitation thesis.
