Investigation of the behavior of limetreated soil with emphasis on laboratory and field implementation technics and microstructural observations is made. Field investigation of a 7-year atmospherically cured embankment, thanks to measurement of sampled materials performances, shows a significant evolution in compressive strength, evidencing the lon...

This paper analyzes the fate of 71 priority and emerging organic contaminants all along the treatment trains of sewage sludge treatment facilities in Paris including dewatering by centrifugation, thermal drying and anaerobic digestion. It aimed at proposing and applying a mass balances calculation methodology to each process and pollutant. This dat...
Cementitious materials shrink when exposed to decreasing relative humidities, which may result in cracking. Shrinkage reducing admixtures (SRAs) can be used to reduce this drying shrinkage. Although many studies have shown that SRAs reduce the surface tension of the pore solution, the effects of SRAs on other pore solution properties and their rela...
For most wood-based product uses it is essential to remove a large part of the water content from wet or green (fresh-cut) wood, to reduce further dimensional variations under varying humidity conditions, improve its mechanical characteristics, and protect it from biological attacks. However, the internal mechanisms of drying are not fully describe...
From Magnetic Resonance Imaging (MRI) measurements allowing to distinguish separately the density distribution of the two phases of the system, we show that bitumen emulsions essentially dry homogeneously, with nevertheless a slight concentration gradient increasing towards the sample free surface exposed to air. Remarkably, despite the resulting l...
There is an increasing interest on wood as it is an environmentally sustainable product (e.g. biodegradable and renewable). Thus, an accurate characterisation of wood properties is of extreme importance as they define the kind of application for which each type of wood can be used. For instance, dry mass of wood is a key parameter itself and is nee...
Les matériaux composites mortier-polymère sont largement utilisés dans l’industrie pour des applications de protection et/ou de réparation de surfaces en béton. En effet, l’ajout de polymère dans les formulations de mortier permet de modifier les propriétés de ces matériaux, en particulier en favorisant leur adhésion tout en réduisant leur perméabi...
