Tests for chemical properties of aggregates - Part 5: Determination of acid soluble chloride salts

This European Standard specifies the procedure for the determination of acid soluble chloride salts which may be present in aggregates. This test is suitable for aggregates where the chloride content does not derive directly from contact with, or immersion in, saline water. Examples of such aggregates are: recycled aggregates containing hydrated cement, where chloride may be bound as calcium chloroaluminates; and some aggregates from desert areas where chloride is occluded within the aggregate particles.

Prüfverfahren für chemische Eigenschaften von Gesteinkörnungen - Teil 5: Bestimmung der säurelöslichen Chloride

Diese Europäische Norm legt ein Verfahren zur Bestimmung säurelöslicher Chloride fest, die in Gesteins-körnungen
vorhanden sein können. Diese Prüfung ist für Gesteinskörnungen geeignet, deren Chloridgehalt
nicht unmittelbar aus dem Kontakt mit oder durch Eintauchen in Salzwasser abzuleiten ist. Beispiele für
Gesteinskörnungen dieser Art sind: rezyklierte Gesteinskörnungen mit abgebundenem Zement, in denen
Chloride als Calciumchloraluminate gebunden sein können sowie einige Gesteinskörnungen aus
Wüstengebieten, in denen Chloride in den Gesteinskörnern eingeschlossen sind.

Essais relatifs aux propriétés chimiques des granulats - Partie 5: Dosage des sels chlorures solubles dans l’acide

La présente Norme européenne spécifie un mode opératoire qui permet de doser les chlorures solubles dans l’acide, susceptibles d’être présents dans les granulats. Le présent essai convient pour des granulats dont la teneur en chlorures n’est pas directement due à un contact avec des eaux salines ou à une immersion dans ces dernières. A titre d’exemple, on peut citer les granulats recyclés contenant du ciment hydraté dans lesquels les chlorures peuvent être liés sous forme de chloro-aluminates de calcium ainsi que certains granulats situés dans les régions désertiques où les chlorures sont inclus dans les particules des granulats.
