Testing hardened concrete - Part 18: Determination of the chloride migration coefficient
This document describes the procedure for obtaining the non-steady-state chloride migration coefficient of specimens of hardened concrete at a specified age. The test procedure does not take into account any interaction of concrete with the saline solution over time. The test result is a durability indicator with respect to the resistance of the concrete investigated against chloride penetration.
The test procedure does not apply to concrete specimens with surface treatments such as silanes.
If the aggregate is electrically conductive or porous this will influence the magnitude of chloride migration. This fact has to be taken into account when establishing threshold values. It prevents comparison of chloride migration values between concretes if the aggregates show a difference of half an order of magnitude (higher or lower) of chloride migration.
Similar influence may be seen when metallic or electrically conducting fibres or particles are present.
Prüfung von Festbeton - Teil 18: Bestimmung des Chloridmigrationskoeffizienten
Dieses Dokument beschreibt das Verfahren für den Erhalt des nicht stabilen Chloridmigrationskoeffizienten von Festbetonprobekörpern eines bestimmten Alters. Das Prüfverfahren berücksichtigt keine Wechsel¬wirkung von Beton mit der Kochsalzlösung über die Zeit. Das Prüfergebnis ist ein Dauerhaftigkeitsindikator in Bezug auf den Widerstand des untersuchten Betons gegen das Eindringen von Chlorid.
Das Prüfverfahren gilt nicht für Betonprobekörper mit Oberflächenbehandlungen wie Silanen.
Wenn die Gesteinskörnung elektrisch leitfähig oder porös ist, wird dies die Größenordnung der Chlorid-migration beeinflussen. Dieser Umstand wird bei der Festlegung von Grenzwerten berücksichtigt. Es verhindert den Vergleich von Chloridmigrationswerten zwischen Betonen, wenn die Gesteinskörnungen eine Differenz von einer halben Größenordnung (höher oder niedriger) der Chloridmigration aufweisen.
Ein ähnlicher Einfluss kann beobachtet werden, wenn metallische oder elektrisch leitende Fasern oder Partikel vorhanden sind.
Essai sur béton durci - Partie 18: Détermination du coefficient de migration des chlorures
Le présent document spécifie le mode opératoire permettant d’obtenir le coefficient de migration des chlorures en régime non stationnaire d’éprouvettes de béton durci à un âge spécifié (voir Annexe A). Ce mode opératoire d’essai ne prend pas en compte l’interaction du béton avec la solution saline au cours du temps. Le résultat d’essai est un indicateur de durabilité en ce qui concerne la résistance du béton étudié à la pénétration des chlorures.
Le mode opératoire d’essai ne s’applique pas aux éprouvettes de béton ayant subi des traitements de surface, par exemple à base de silanes.
Si le granulat ou tout autre élément incorporé (notamment des fibres métalliques ou des particules conductrices) sont électriquement conducteurs, cela va influer sur l’ampleur de la migration des chlorures. Ce fait est pris en compte lors de l’établissement des valeurs seuils. En effet, la comparaison des valeurs de migration des chlorures entre les bétons est impossible si les granulats induisent une différence d’un demi-ordre de grandeur (en plus ou en moins) en matière de migration des chlorures.
