(Main)Testing hardened concrete - Part 12: Determination of the carbonation resistance of concrete - Accelerated carbonation method
Testing hardened concrete - Part 12: Determination of the carbonation resistance of concrete - Accelerated carbonation method
This procedure is a method for evaluating the carbonation resistance of concrete using test conditions that accelerate the rate of carbonation. After a period of preconditioning, the test is carried out under controlled exposure conditions using an increased level of carbon dioxide.
NOTE The test under reference conditions takes a minimum of 112 days comprising a minimum age of the specimen prior to conditioning of 28 days, a minimum conditioning period of 14 days and an exposure to increased carbon dioxide levels of 70 days.
This procedure is not a method for the determination of carbonation depths in existing concrete structures.
Prüfung von Festbeton - Teil 12: Bestimmung des Karbonatisierungswiderstandes von Beton - Beschleunigtes Karbonatisierungsverfahren
Dieses Verfahren repräsentiert eine Methode für die Beurteilung des Karbonatisierungswiderstandes von Beton unter solchen Prüfbedingungen, die die Karbonatisierungsgeschwindigkeit beschleunigen. Nach einer Vorbehandlungsphase wird die Prüfung unter geregelten Bedingungen in Form der Beanspruchung durch eine erhöhte Kohlenstoffdioxidkonzentration in der Umgebungsluft durchgeführt.
ANMERKUNG Unter Referenzbedingungen dauert diese Prüfung mindestens 112 Tage, wobei diese Zeitspanne die mindestens 28 tägige Alterung des Probekörpers vor der Klimatisierung, seine mindestens 14 Tage dauernde Klimatisierung und seine 70 tägige Beanspruchung durch erhöhte Kohlenstoffdioxidkonzentrationen umfasst.
Dieses Verfahren eignet sich nicht zur Bestimmung der Karbonatisierungstiefen in bereits bestehenden Betontragwerken.
Essais pour béton durci - Partie 12 : Détermination de la résistance à la carbonatation du béton - Méthode de la carbonatation accélérée
Le présent mode opératoire est une méthode pour l’évaluation de la résistance à la carbonatation d’un béton en utilisant des conditions d’essai qui accélèrent la vitesse de carbonatation. Après une période de préconditionnement, l’essai est réalisé dans des conditions d’exposition contrôlées avec une teneur plus élevée en dioxyde de carbone.
NOTE L’essai dans les conditions de référence nécessite au minimum 112 jours, l’âge minimal de l’éprouvette avant le conditionnement étant de 28 jours, plus une période minimale de conditionnement de 14 jours et une exposition de 70 jours à des teneurs élevées en dioxyde de carbone.
Ce mode opératoire ne permet pas de déterminer la profondeur de carbonatation des structures en béton existantes.
