The corrosion of steels is one of the principal causes of degradation of reinforced concrete structures, especially in front of the sea. This degradation is due to the diffusion of chloride ions that can occur in the structures immersed in the seawater, those undergoing tidal cycles and also those subjected to the sea spray. The corrosion can also be due to the carbonation process of the concrete, which is responsible for decreasing of the pH and consequently the depassivation of the steels. This thesis proposes: 1- a physicochemical model to describe the penetration of aggressive agents in the first period of steel corrosion. This so-called « incubation » period corresponds to the period during which the transfer of aggressive species occurs in the concrete. In order to clearly identify the transport parameters of this macroscopic model: 2- a multi-scale approach is implemented to consider the diffusion in concretes. This approach is based on taking into account the detailed description of the microstructure of the concrete (constituents and morphology) by upscaling methods. This multi-scale approach is intended to be the most comprehensive with the consideration of the influence of the water-to-binder ratio of the cement paste, the properties of the aggregates and the transition zone between the cement paste and the aggregates. After identifying all the input parameters, the macroscopic physico-chemical model is used to evaluate the service life of a concrete subjected to coupling carbonation - chlorides in unsaturated medium. Following a validation of the model compared to experimental results, several applications of this model are presented. Show less

Researcher: Concrete is a porous material that can be subjected to aggressive agents like chloride and de-icing salts. These agents result in the corrosion of reinforcing bars, which is the principal reason of the deterioration of reinforced concrete structures. Thus the modeling of chloride transports phenomena present a great interest in the development of the durability of civil engineering structures. This research project has aims to : 1- develop a finite element for modeling these phenomena 2- perform numerical simulations of chloride transport in a cementations material. In our study, the cementations material is observed at the mesoscopic scale. Show less

- Engineer: The grand ambition for King Abdul-Aziz Center for knowledge and Culture is that of marking a new area in the Kingdom of Saudi Arabia. It will subsequently be a great achievement for the oil company Saudi Aramco. In undertaking the design for the King Abdulaziz center for knowledge & culture, Snohetta has developed a design team of the leading industry experts from around world. The progress of the design team has been mapped using web graphs. With an overview web in each weekly report and the additionally individual webs covering each design discipline in the monthly reports. We can summarize the activities done in the training: -Taking courses about safety rules. -3D shop drawings -Site investigation -Finishing works (Tilling-Waterproofing) -Some MEP activities AutoCAD 3D workshop: As we see in the exterior design of the project KACWC, AutoCAD 3D create intelligent models for several structures. Finishing work: Tilling Show less
