Porosity of concrete / Fan Zhang in European journal of environmental and civil engineering, Vol. 16 N° 3-4 (Mars/Avril 2012) 

Public ISBD [article]  in European journal of environmental and civil engineering > Vol. 16 N° 3-4 (Mars/Avril 2012) . - pp. 311-321 Titre : Porosity of concrete : Influence of test conditions and material variability Type de document : texte imprimé Auteurs : Fan Zhang, Auteur ; Thomas Rougelot, Auteur ; Nicolas Burlion, Auteur Année de publication : 2012 Article en page(s) : pp. 311-321 Note générale : Génie Civil Langues : Anglais (eng) Mots-clés : Variability  Spatial  variability  Concrete  Porosity  Experimental  biases Résumé : The prediction of the service lifetime of civil engineering structures needs an appropriate comprehension and quantification of the physical, chemical and mechanical processes associated with the durability of structural reinforced concrete. In particular, the porosity is an essential property involved in degradation of concretes. Also, the development of a probabilistic approach could enhance estimations of service lifetime. Experimental tests are therefore performed in the framework of project APPLET and aim at quantifying variabilities linked to concrete itself and its setting in a real structure. A spatial variability and the effect of the drying protocol for the measurement of porosity have been highlighted.
