The response of structures exposed to fire is highly dependent on the type of fire that occurs, which is in turn very dependent on the compartment geometry. In the frame of the European RFCS TRAFIR project, CFD simulations using FDS software were carried out to analyse the influence of compartment geometry and the interaction with representative fu...
Internal sulfate attack can be caused by the gypsum residues present in fine recycled aggregates (FRA). Asopposed to the better known external sulfate attack or Delayed Ettringite Formation (DEF), the sulfates inthis context are provided by a gypsum contamination of the aggregates. Mortars made with contami-nated FRA were subjected to different con...
The concrete based patrimony is subjected to different deterioration mechanisms, including steel corrosion induced by carbonation or chloride ion diffusion. Hydrophobic product may be used for protecting concrete structures against water ingress. No data are available on the correlation between quality of hydrophobic agent, concrete substrate prope...
Energy consumption in buildings results in CO2 emissions and it is necessary to reduce energy consumption thus its related emissions. This research is included in the Wal-e-cities project, which is funded by the European Regional Development Fund (ERDF) and aims to create tools that facilitate the transition toward smart territory. The annual heat ...
Modelling numerically natural phenomena like river flows, flows on hydraulic structures or groundwater flows, helps engineers quantifying them in order to organise human activities on the one hand and design mitigation measures on the other hand. These models take, as input data, quantities that are uncertain because of their variability in time an...

La sauvegarde des bâtis historiques a pour objectif la préservation pérenne d'un patrimoine, symbole de l’identification culturelle d’un peuple ou d’une nation. La conservation de ce patrimoine est d’une importance majeure pour un pays, une région, une ville ou un quartier dans le sens qu’il permet à une société de s’identifier à son histoire au tr...
The use of recycled materials and porous aggregates such as rubber crumbs and volcanic gravel (pozzolana) for the drainage layer can lead to improving thermal behaviour of the green roofs. On the other hand, the thermal performances of green roofs can be affected by the thickness of substrate and drainage layer. Therefore, the main objective of thi...
Fine recycled aggregates are an important waste stream coming from the demolition of old concrete structures. They are up to now not valorized because of an increased water absorption, lower density and higher fines content compared to natural aggregates. Moreover, they often have a high sulfate concentration. These sulfates could have originated f...
This paper deals with the behaviour under fire of vertical walls made of steel sheet piles in retaining walls close to, for example, a traffic road or an industrial facility or in underground structures such as car parks or cut and cover tunnels. For the later situation, the sheet pile walls support not only the horizontal pressure from the ground ...
