Comprehensive modeling of chloride ion and water ingress into concrete considering thermal and carbonation state for real climate / David Conciatori in Cement and concrete research, Vol. 40 N° 1 (Janvier 2010)  

Public ISBD [article]  inCement and concrete research > Vol. 40 N° 1 (Janvier 2010) . - pp. 109-118 Titre : Comprehensive modeling of chloride ion and water ingress into concrete considering thermal and carbonation state for real climate Type de document : texte imprimé Auteurs : David Conciatori, Auteur ; Francine Laferrière, Auteur ; Eugen Brühwiler, Auteur Article en page(s) : pp. 109-118 Note générale : Génie Civil Langues : Anglais (eng) Mots-clés : Adsorption Carbonation Diffusion Chloride Thermal analysis Finite element Index. décimale : 691 Matériaux de construction. Pièces et parties composantes Résumé : This article presents a comprehensive modeling of temperature, carbonation, water and chloride ions transport in cover concrete using the transport model “TransChlor”. The TransChlor transport model employs weather data and chloride ion concentrations present on the concrete surface to predict the temporal and spatial evolution of the presence of chloride ion concentrations in the cover concrete pores. The main features of the TransChlor model are presented and validated. The TransChlor model has been calibrated using experimental data on liquid water movement in concrete of different permeabilities under realistic microclimatic conditions. Chloride ion transport is validated by means of experimental results obtained from a newly developed chloride ion optical fiber based sensor.
