Tests for thermal and weathering properties of aggregates - Part 6: Determination of resistance to freezing and thawing in the presence of salt (NaCl)
This European Standard specifies a method of assessing the frost resistance of an aggregate when it is subjected to the cyclic action of freezing and thawing in the presence of 1 % solution of NaCl in de-ionized or distilled water.
The results of this test provide a means for assessing an aggregate’s resistance to this form of weathering in areas where frequent freeze-thaw cycling occurs with seawater sprays or abundant de-icers conditions, and where result values of EN 1367-1 test method do not describe correctly aggregate performance in extreme conditions.
This European Standard gives the option to control the thawing sequence either by immersion in water or by using air circulation in the low temperature cabinet to obtain the required reference temperature.
This test method is applicable to coarse aggregates or to coarse aggregates' fractions of all-in materials. This method is not appropriate for lightweight aggregates covered by EN 13055 or aggregates which can not be submitted to 110 °C oven drying.
Prüfverfahren für thermische Eigenschaften und Verwitterungsbeständigkeit von Gesteinskörnungen - Teil 6: Beständigkeit gegen Frost-Tau-Wechsel in der Gegenwart von Salz (NaCl)
Diese Europäische Norm legt ein Prüfverfahren zur Beurteilung der Frostbeständigkeit von Gesteinskörnungen
bei zyklischer Frost-Tau-Wechselbeanspruchung in Anwesenheit einer 1%igen Lösung von NaCl
in entionisiertem oder destilliertem Wasser fest.
Die Prüfergebnisse ermöglichen die Beurteilung der Beständigkeit einer Gesteinskörnung gegen diese Art der
Witterungsbeanspruchung in Bereichen, die häufig der Beanspruchung durch Frost-Tau-Wechsel und der
Einwirkung von Salzgischt oder Enteisungsmitteln ausgesetzt sind und in denen die Ergebniswerte des Prüfverfahrens
nach EN 1367-1 das Leistungsverhalten von Gesteinskörnungen unter extremen Bedingungen
nicht korrekt beschreiben.
Diese Europäische Norm stellt es frei, ob die Regelung in der Auftauphase mit Hilfe eines Wasserbades oder
durch Luftumwälzung in einem Wärmeschrank erfolgt, um die geforderte Bezugstemperatur einzustellen.
Dieses Prüfverfahren ist auf grobe Gesteinskörnungen oder auf die Grobkornanteile von Gesteinskörnungen
anwendbar, die alle Korngemische enthalten. Dieses Prüfverfahren ist nicht für leichte Gesteinskörnungen
nach EN 13055 geeignet oder für Gesteinskörnungen, die nicht einer Ofentrocknung bis 110 °C unterzogen
werden können.
Essais pour déterminer les propriétés thermiques et l'altérabilité des granulats - Partie 6: Résistance au gel-dégel au contact du sel
La présente Norme européenne spécifie une méthode d’essai pour évaluer la résistance au gel des granulats lorsqu’ils sont soumis à un cycle de gel-dégel au contact d’une solution de NaCI à 1 % dans de l’eau déminéralisée ou distillée.
Les résultats apportent un moyen d’évaluer la résistance du granulat à cette forme d’altération dans des zones où il se produit régulièrement des cycles de gel-dégel, en particulier dans les lieus où les embruns et le déverglaçage sont fréquents. Et pour lesquelles les résultats de la norme EN 1367-1 ne décrivent pas correctement les performances des granulats en condition extrême.
La présente Norme apporte la possibilité de contrôler le processus de dégel dans l’armoire soit par ventilation, soit par circulation d’eau, afin d’obtenir une température correcte de l’échantillon de référence.
L’essai s’applique aux gravillons et aux classes granulaires des gravillons de la grave.
Cet essai n’est pas approprié pour les granulats concernés par la norme EN 13055 ni pour les granulats qui ne peuvent supporter un sèchage à 110 °C.
