Projets de recherche en cours et subventions
- FRQNT-ÉQUIPE : projet SGOMI-Marin (2023-2026)
A major five-year research program is being developed to determine the microclimate or exposure of structures to their environment. This research program is based on a project in partnership with the FRQNT, the CRIB concrete infrastructure research center (Université Laval), and the Coastal Engineering Research Chair (UQAR). The aim of this project is to develop climate models to predict structural aging and durability in a sustainable development context. The deterioration of concrete in marine environments (especially along the river Saint-Laurent) depends on the exposure of the structure to its environment. The migration of a multitude of ions contained in saline waters can provoke chemical reactions with the various concrete constituents. The state of cracking can also accelerate the diffusion process in these environments.
The success of this R&D program is strongly linked to the teamwork of university researchers from UQAR, Laval University, Montreal Polytechnique and McGill University, experts from different domains from finance management to structural engineering. Therefore, we are looking for a highly motivated PhD student (or MSc student) with a strong numerical modeling profile, enthusiasm in coastal engineering and strong interest in multidisciplinary study. The candidate should demonstrate solid background in civil engineering and experimental sensibility. Good knowledge of chemistry and/or concrete chemistry appreciated. Fluency in English or French appreciated. Any programming or numerical simulation experience would be an asset.
Interested and qualified candidates should send their curriculum vitae, the contact information of two referees and their transcripts to: Cette adresse courriel est protégée contre les robots spammeurs.
