Admixtures for concrete, mortar and grout - Part 3: Admixtures for masonry mortar - Definitions, requirements, conformity and marking and labelling
This European Standard defines and specifies the requirements and conformity criteria for admixtures for use in cement based masonry mortar. It covers two types of admixtures, long term retarding and air entraining/plasticising which are used in ready-mixed and site made masonry mortars. Provisions for the use of admixtures for masonry mortar are not part of this European Standard but are covered by EN 998-1 and EN 998-2.
Zusatzmittel für Beton, Mörtel und Einpressmörtel - Teil 3: Zusatzmittel für Mauermörtel - Definitionen, Anforderungen, Konformität, Kennzeichnung und Beschriftung
Diese Europäische Norm definiert und legt Anforderungen und Konformitätskriterien für Zusatzmittel für zementgebundenen Mauermörtel fest.
Sie gilt für zwei Arten von Zusatzmitteln, Erstarrungsverzögerer für langzeitverzögerte Mauermörtel und Luftporenbildner/Betonverflüssiger, die sowohl für Mörtel, der fertig gemischt auf die Baustelle geliefert wird, als auch für Mörtel, der auf der Baustelle hergestellt wird, verwendet werden.
Festlegungen zur praktischen Anwendung von Zusatzmitteln für Mauermörtel sind nicht Bestandteil dieser Europäischen Norm, sondern werden durch EN 998-1 und EN 998-2 erfasst.
Adjuvants pour béton, mortier et coulis - Partie 3: Adjuvants pour mortier de montage - Définitions, exigences, conformité, marquage et étiquetage
La présente Norme européenne définit et précise les exigences et les critères de conformité pour les adjuvants utilisés dans le mortier à maçonner à base de ciments.
Il s'applique à deux types d'adjuvants, les adjuvants fortement retardateurs de prise et les adjuvants entraîneurs d'air / plastifiants utilisés dans le mortier prêt à l'emploi ainsi que dans le mortier fabriqué sur chantier.
Les dispositions relatives à l’utilisation d'adjuvants de mortier à maçonner ne font pas partie de la présente norme européenne, mais de l’EN 998-1 et de l'EN 998-2.

Ta evropski standard določa ter opredeljuje zahteve in merila za skladnost za dodatke pri uporabi v zidarski malti, ki temelji na cementu. Pokriva dve vrsti dodatkov, dolgoobstojne in aerirane dodatke/plastifikatorje, ki se uporabljajo v svežih mešanicah in zidarski malti, pripravljeni na mestu samem. Določbe za uporabo dodatkov za zidarsko malto niso del tega evropskega standarda; vključene so v standarda EN 998-1 in EN 998-2.
