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 siliceous fly ash, as defined in 3.2, for use as a type II addition for production of concrete conforming to EN 206-1. Fly ash according to this document may also be used in mortars and grouts.
Fly ash produced with other types or higher percentages of co-combustion materials than those provided for in Clause 4 is outside the scope of this European Standard.
It is beyond the scope of this European 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. Regarding such provisions, reference should be made to other European or national standards for concrete, such as EN 206-1.
Flugasche für Beton - Teil 1: Definition, Anforderungen und Konformitätskriterien
Diese Europäische Norm 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 nach EN 206 1 verwendet wird. Flugasche entsprechend dieses Dokuments 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 Europäischen 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 Europäischen Norm. Für diesbezügliche Festlegungen wird auf andere Europäische oder nationale Normen für Beton, wie z. B. EN 206 1, verwiesen.
Cendres volantes pour béton - Partie 1: Définition, spécification et critères de conformité
La présente Norme européenne définit les exigences relatives aux propriétés chimiques et physiques ainsi qu’aux modes opératoires de contrôle de la qualité pour les cendres volantes siliceuses, telles que définies en 3.2, utilisées comme addition de Type II pour la production de béton, en accord avec l’EN 206-1. Les cendres volantes selon le présent document peuvent également être utilisées dans des mortiers et des coulis.
Les cendres volantes produites avec d’autres types ou des teneurs plus élevées de co-combustibles que ceux prévus à l’Article 4 n’entrent pas dans le domaine d’application de la présente Norme européenne.
Les règles concernant l’utilisation pratique des cendres volantes dans la production 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 du domaine d’application de la présente Norme européenne. En ce qui concerne ces règles, il convient de se référer à d’autres Normes européennes ou nationales traitant du béton, comme l’EN 206-1.
Elektrofiltrski pepel - 1. del: Definicije, specifikacije in merila skladnosti
Ta evropski standard navaja zahteve za kemijske in fizikalne lastnosti ter postopke za kontrolo kakovosti za kremenasti elektrofiltrski pepel, ki je opredeljen v 3.2, za uporabo kot dodatek tipa II za izdelavo betona, vključno z na gradbišču zmešanim betonom ali predhodno zmešanim strukturnim betonom, ki je skladen s standardom EN 206-1. V skladu s tem dokumentom se lahko elektrofiltrski pepel uporablja tudi v malti in zalivni masi. Elektrofiltrski pepel, ki se proizvaja z drugimi vrstami ali višjimi odstotki snovi za sosežig, ki niso navedeni v točki 4, ne spada na področje uporabe tega standarda. Ta standard tudi ne podaja določb glede praktične uporabe elektrofiltrskega pepela pri proizvodnji betona, tj. zahtev v zvezi s sestavo, mešanjem, polaganjem, sušenjem itd. betona, ki vsebuje elektrofiltrski pepel. Te določbe so obravnavane v drugih evropskih ali nacionalnih standardih za beton, na primer v standardu EN 206-1.

When using fly ashes conforming to this document, it should be noted that, apart from the effect from the pozzolanicity of the fly ash, certain properties of fresh and hardened concrete may be affected. Where relevant, such effects need to be considered in concrete mix design (see EN 206-1). SIST EN 450-1:2013
