Public ISBD [article]  in European journal of environmental and civil engineering > Vol. 16 N° 3-4 (Mars/Avril 2012) . - pp. 298-310 Titre : Study of electrical resistivity : Variability assessment on two concretes: protocol study in laboratory and assessment on site Type de document : texte imprimé Auteurs : J.F. Lataste, Auteur ; T. De Larrard, Auteur ; F. Benboudjema, Auteur Année de publication : 2012 Article en page(s) : pp. 298-310 Note générale : Génie Civil Langues : Anglais (eng) Mots-clés : Electrical  resistivity  Concrete  Variability  Measurements Résumé : This article presents electrical resistivity measurement on concrete. The first part presents the study of a lighter protocol for measuring electrical resistivity, allowing investigations of a large number of specimens, without degradation of the quality of final results. The second part is based on measurements made on two concretes cast regularly during one year each, on two sites. Measurements done to assess the different variability sources distinguish variability linked to the measurement of those related to the material. The third part of the article compares the laboratory measurements to those made on site. Finally, all the results reflected the interests of the resistivity measurement because of low variability obtained, and consistency between results.
