Public ISBD [article]  inEuropean journal of environmental and civil engineering > Vol. 15 N° 5 (Mai 2011) . - pp. 759-772 Titre : Characterisation of geometrical properties of concrete using passive infrared thermography Type de document : texte imprimé Auteurs : Mathilde Larget, Auteur ; Denys Breysse, Auteur ; colette Sirieix, Auteur Année de publication : 2011 Article en page(s) : pp. 759-772 Note générale : Génie Civil Langues : Français (fre) Mots-clés : Infrared thermography Modelling Fourier’s equation Concrete Non-destructive testing Index. décimale : 624 Constructions du génie civil et du bâtiment. Infrastructures. Ouvrages en terres. Fondations. Tunnels. Ponts et charpentes Résumé : This paper talks about thermal response of concrete during natural warming up. An experimental study is carried out. Experimental warming up curves are compared with numerical modelling based of the Fourier equation. In the last part we study the influence of density, specific heat and thermal conductivity on diffusivity coefficient. Study proves that infrared passive thermography performed to monitor the natural warming up of concrete is sensitive to variable thickness of concrete.
