Séminaire MONARIS | Mario Marchetti "Implementation of Raman spectroscopy to civil engineering materials"

Séminaire chercheur invité par le MONARIS

Mario Marchetti (directeur de recherche à l'Université Gustave Eiffel, Champs-sur-Marne)

présentera une conférence intitulée
"Implementation of Raman spectroscopy to civil engineering materials"

For years, Raman spectroscopy was dedicated to laboratory investigations and to materials with given degrees of heterogeneities and complexity, from biological materials to semi-conductors or sophisticated metallic alloys. Nevertheless, materials dedicated to civil engineering have barely been investigated by means of Raman spectroscopy. It has been implemented since the late seventies, and encountered in many studies till then, although not all the time the cornerstone of the investigations. In this presentation, some results of the benefits of implementing Raman spectroscopy will be given. It consisted in first characterizing specific phases present in cementitious materials, up to a continuous monitoring of some alteration processes such as carbonation or sulphatic attack, or the characterization of an archeological sample, with the benefits of chemometrics.
