Characterisation of geometrical properties of concrete using passive infrared thermography / Mathilde Larget in European journal of environmental and civil engineering, Vol. 15 N° 5 (Mai 2011) 

Public ISBD [article]  in European 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.

Quality of NDT measurements and accuracy of concrete physical properties quantitative assessment / Denys Breysse in European journal of environmental and civil engineering, Vol. 15 N° 4 (Avril 2011)

Infrastructures. Ouvrages en terres. Fondations. Tunnels. Ponts et charpentes Résumé : Assessing concrete condition is of major interest either for looking at weak or more damaged areas, or for reliability computations. NDT measurements provide a valuable way of offering a quick overview on the material condition. One of their main weaknesses is that their results cannot be directly linked with material properties. This paper presents how a collaborative research programme has been developed such as: (a) to select the best appropriate measurement techniques, (b) identify calibration laws enabling the quantitative material condition assessment, (c) identify possible valuable combinations of techniques. This strategy is applied to laboratory specimen data as well as to on site data. A focus is also placed on the reliability of the material condition assessment.
