Test methods for fibres in concrete - Part 1: Reference concretes
This European Standard specifies the composition and characteristics of reference concretes used to evaluate the performance of fibres in concrete.
The purpose of the reference concrete is to determine the general suitability of a fibre for use in concrete.
NOTE The end user needs to satisfy themselves about the effectiveness of the fibre in their own concrete.
Prüfverfahren für Fasern in Beton - Teil 1: Referenzbetone
Dieser europäische Norm-Entwurf legt die Zusammensetzung und die Eigenschaften von Referenzbetonen fest, die zur Beurteilung der Leistung von Fasern in Beton zu verwenden sind.
Méthodes d'essai des fibres dans le béton - Partie 1: Bétons de référence
La présente Norme européenne spécifie la composition et les caractéristiques des bétons de référence utilisés pour évaluer la performance des fibres incorporées dans le béton.
Les bétons de référence servent a déterminer l’aptitude générale d’une fibre a etre incorporée dans le béton.
NOTE L’utilisateur final doit vérifier lui-meme l’efficacité de la fibre dans son propre béton.
