10 Knowledge of the transport properties of damaged concrete in marine environments is 11 essential for predicting its durability. The objective of this study was to fill this gap by 12 correlating the change in permeability and chloride diffusivity with an increasing uniaxial 13 load on ordinary concrete (OC) and high performance concrete (HPC). C...
The objective of this research work is to model the influence of deformation and damage on the permeability and retention properties of cracked porous media. This is achieved thanks to the introduction of microscale information into a macroscopic damage model. To this end, the Pore Size Distribution (PSD) of the material is coupled to the mechanica...
La maitrise du colmatage des membranes des bioréacteurs à membranes (BRM) est un point clé du développement de cette technologie car elle pourrait permettre des réductions significatives de consommation d’énergie. On peut considérer deux catégories de colmatage pour la modélisation de la filtration, chacune correspondant à une échelle de temps diff...
This paper deals with the recent research results obtained through SOTREDI research project, “SOil TREatment for DIkes” undertaken by the Lhoist Group, a lime producer, in collaboration with several research centres and universities. Lime-treatment of soils is a process that improves the workability of clayey materials and imparts them strong mecha...
The present paper discusses the hydro mechanical behavior of activated Ca–bentonite mixed with two solublepolyelectrolyte powder polymers. To understand better the clay polymer interaction, swelling, water adsorptionand hydraulic performance are studied. Synthetized leachate (LS) is used to reproduce the hydrochemical phenomenain the system. Hydrau...

This paper investigates whether durability indicators (DIs), more specifically transport properties, can be assessed by simple methods, e.g. direct experimental methods or indirect methods based on analytical formulas, for every type of concrete. First the results of electrical resistivity and apparent chloride diffusion coefficient obtained by dir...
This paper deals with the sedimentation of highly concentrated sediment suspensions (cohesive as well as non-cohesive) and the beginning of the consolidation of cohesive sediments. Based on a comparison of existing empirical formulas and experimental data, the particle Reynolds number was shown to be of importance for the behaviour of particularly ...
