Etude expérimentale du frottement glace-structure à l'échelle centimétrique
Offshore structures constructed in polar regions are exposed to the drift of ice which generates dynamic loads at the ice-structure interface. The intensity and the... -
EXPERIMENTAL STUDY AND NUMERICAL ANALYSIS OF CRACK OPENING IN CONCRETE
It is commonly accepted that there is a size effect on the nominal resistances of quasi-brittle materials such as cementitious materials. This effect must be taken... -
Damage analysis of reinforced concrete structures : hybrid substructuring met...
The seismic analysis of civil engineering structures is a major problem for the safety of the persons and the sustainability of the structures. The experimental study... -
Multi-technique investigation of calcium hydroxide crystals at the concrete s...

Experimental study on gas and water relative permeability of cementitious mat...
This dissertation was devoted to study gas and water relative permeability and transfer of water in partially saturated cementitious materials. The gas relative... -
Characterization of cement paste by ultrasonic methods
In this thesis, we present an experimental study including, besides the destructive measurements usually implemented for the characterization of cementitious... -
Superficial colouring of fresh concrete through the demoulding agent : compar...
Concrete is an achromatic material that can be coloured through two main techniques: introduction of pigments in the bulk of the material, or application of a coloured... -
Contribution about the behavior of fresh cement based material
Ce rapport est une synthèse de mon activité de recherche post-thèse au LG2M à Lorient. Les recherches exposées se situent dans le domaine de la rhéologie des matériaux... -

Physical and chemical binding in carbonated and non-carbonated concretes : in...
Carbonation and chloride ingress are the main causes of reinforced concrete degradation. A lot of studies describe these two phenomena separately but only few studies... -
Experimental study of the permeability of concrete under variable thermal and...
The main objective of this study is to evaluate the variable thermal and hydric effect, with fissuration effect on the hydraulic behaviour of two concretes. Many... -
Contribution of the Acoustic Emission technique in the understanding and the ...
In order to design reliable concrete structures, prediction of long term behaviour of concrete is important. In fact, creep deformation can cause mechanical... -
Explicit modeling of fire induced spalling of concrete : a thermo-hydro-mecha...
In the recent years, there were major tunnels fires which caused fatalities and severe traffic restrictions. In such extreme conditions (temperatures exceeding 1200 °C... -
Study of risk of developing a delayed ettringite formation and its consequenc...
Delayed ettringite formation (DEF) in concrete structures is a pathology that can develop when special conditions on the concrete composition, the thermal conditions... -
Micromechanical modeling and numerical simulation of creep in concrete taking...
Concrete is a complex heterogeneous material whose deformations include a delayed part that is affected by a number of factors such as temperature, relative humidity...
