Fly ash for concrete - Part 1: Definition, specifications and conformity criteria

This European Standard specifies requirements for the chemical and physical properties as well as quality control procedures for fly ash, as defined in clause 3.2, for use as a type II addition for preparation of concrete, mortar and grout, including in particular cast-in-situ or prefabricated structural concrete conforming to EN 206-1. )
It is, however, beyond the scope of this standard to specify provisions governing the practical application of fly ash in the production of concrete, i.e. requirements concerning composition, mixing, placing, curing etc. of concrete containing fly ash. As regards such provisions, reference should be made to other European or national standards for concrete, such as EN 206-1.
Fly ash for use in the manufacture of cements according to EN 197-1 is outside the scope of this standard.

Flugasche für Beton - Teil 1: Definition, Anforderungen und Konformitätskriterien

Dieses Dokument legt Anforderungen an die chemischen und physikalischen Eigenschaften sowie Verfahren für die Güteüberwachung von siliciumreicher Flugasche nach der Definition in 3.2 fest, die als Zusatzstoff Typ II für die Herstellung von Beton, einschließlich insbesondere auch von Ortbeton oder Betonfertigteilen für tragende Zwecke, nach EN 206 1 verwendet wird. Flugasche entsprechend dieser Norm kann auch in Mörteln und Einpressmörteln verwendet werden.
Flugasche, die mit anderen Typen oder höheren Prozentsätzen von Mitverbrennungsstoffen als in Abschnitt 4 vorgesehen hergestellt wird, ist nicht Gegenstand dieser Norm.
Festlegungen für die praktische Verwendung von Flugasche bei der Betonherstellung, d. h. Anforderungen an die Zusammensetzung, das Mischen, den Einbau, die Nachbehandlung usw. von Flugasche enthaltendem Beton, sind nicht Gegenstand dieser Norm. Für diesbezügliche Festlegungen wird auf andere Europäische oder Nationale Normen über Beton, wie z. B. EN 206 1, verwiesen.

Cendres volantes pour beton - Partie 1: Définition, spécifications et critères de conformité

La présente norme européenne définit les exigences relatives aux propriétés chimiques et physiques ainsi qu'aux procédures de maîtrise de la qualité pour les cendres volantes, telles que définies en 3.2, utilisées comme addition de Type II pour l'élaboration de béton, de mortier ou de coulis, et notamment, de béton de structure coulé en place ou préfabriqué, en accord avec l'EN 206-1 ).
Les règles concernant l'utilisation pratique des cendres volantes dans l'élaboration du béton, c'est-à-dire les dispositions concernant la composition, le malaxage, la mise en place, la cure etc. de bétons qui contiennent des cendres volantes, sortent toutefois du champ d'application de la présente norme. Pour ces règles, il convient de se référer à d'autres normes européennes ou nationales traitant du béton, comme l'EN 206-1 par exemple.
Les cendres volantes destinées à être utilisées pour la fabrication de ciments selon l'EN 197-1 ne sont pas couvertes par la présente norme.
