Round-Robin Test on methods for determining chloride transport parameters in concrete

Abstract

[FR]Cet article comprend les résultats des essais inter-laboratoires sur les méthodes de mesure de la pénétration des chlorures dans le béton, effectués par la Commission technique RILEM 178-TMC: “Testing and Modelling Chloride Penetration in Concrete”. Les participants étaient issus de 27 laboratoires répartis sur différents continents. On a utilisé 4 mélanges de béton différents fabriqués avec différents types de ciment, ainsi que␣13 méthodes d’essais utilisant des échantillons en triple exemplaire. Les méthodes d’essais ont été divisées en 4 familles: essais de Diffusion naturelle (D), essais de Migration (M), essais de Résistivité électrique (R) et méthodes Colorimétriques (C). Le traitement statistique a été fait conformément à la norme Standard ISO 5725-2:1994 intitulée: «Determination of the accuracy (trueness and precision) of measurement methods and results. Part 2: Basic method for the determination of the repeatability and reproducibility of a standard measurement method (Détermination de la précision des méthodes de mesure et des résultats. Partie 2: Méthode essentielle de détermination de la répétabilité et de la reproductibilité d’une méthode classique de mesure)». Pour faire une analyse plus détaillée, on a complété l’étude avec l’évaluation de 4 indicateurs d’intérêt et plusieurs sous-indicateurs. L’évaluation finale a été effectuée au moyen de la classification de l’importance des données de chaque indicateur en tenant en compte des facteurs d’importance.

[EN]This paper presents the results of a Round-Robin Test on methods for determining chloride transport parameters in concrete, carried out by the Technical Committee TC 178-TMC: “Testing and Modelling Chloride Penetration in Concrete” in which 27 different laboratories around the world have participated, using 13 different methods, in triplicate specimens, for 4 different mixes of concrete cast with different binders. Four different groups of methods have been tested: Natural diffusion methods (D), Migration methods (M), Resistivity methods (R) and Colourimetric methods (C). The statistical treatment of the data has been carried out according to the International Standard ISO 5725-2:1994 for the determination of the accuracy (trueness and precision) of measurement methods and results. Part 2: Basic method for the determination of the repeatability and reproducibility of a standard measurement method. In order to make an evaluation of these methods, four indicators have been identified and within each of them, several sub-indicators have been assigned. According to this system of classification, the methods have been classified following each indicator (trueness, precision, relevance and convenience), and also globally, by assigning different factors of importance, F.I., to the different indicators.
