Admixtures for concrete, mortar and grout - Part 7: Shrinkage reducing admixtures - Definitions, requirements, conformity, marking and labelling
This document specifies definitions, characteristics and requirements for shrinkage reducing admixtures for use in concrete.
It covers admixtures for plain, reinforced and prestressed concrete which are used in site mixed, ready mixed concrete and precast concrete.
The performance requirements in this document apply to admixtures used in concrete of normal consistence. They may not be applicable to admixtures intended for other types of concrete such as semi dry and earth moist mixes.
Provisions governing the practical application of admixtures in the production of concrete, i.e. requirements concerning composition, mixing, placing, curing etc. of concrete containing admixtures are not part of this document.
Zusatzmittel für Beton, Mörtel und Einpressmörtel - Teil 7: Schwindreduzierer - Definitionen, Anforderungen, Konformität, Kennzeichnung und Beschriftung
Dieses Dokument legt Begriffe, Eigenschaften und Anforderungen für Schwindreduzierer zur Verwendung in Beton fest.
Es gilt für Zusatzmittel für unbewehrten Beton, Stahl- und Spannbeton, die für Ort- und Transportbeton sowie für Beton für Fertigteile verwendet werden.
Die Leistungsanforderungen nach diesem Dokument gelten für Zusatzmittel, die für Beton mit üblicher Konsistenz verwendet werden. Sie sind möglicherweise nicht auf Zusatzmittel für andere Arten von Beton, wie z. B. halbtrockene und erdfeuchte Mischungen, anwendbar.
Bestimmungen zur praktischen Anwendung von Zusatzmitteln bei der Herstellung von Beton, d. h. Anforderungen bezüglich der Zusammensetzung, der Mischung, der Verarbeitung und der Nachbehandlung usw. von Beton, der Zusatzmittel enthält, sind nicht Gegenstand dieses Dokuments.
Adjuvants pour bétons, mortier et coulis - Partie 7 : Agent réducteur de retrait - Définitions, exigences, conformité, marquage et étiquetage
Le présent document spécifie les définitions, les propriétés et les exigences relatives aux agents réducteurs de retrait destinés à être utilisés dans le béton.
Il couvre les adjuvants pour bétons non armés, armés et précontraints utilisés dans les bétons fabriqués sur chantier, prêts à l'emploi et préfabriqués.
Les exigences de performance contenues dans le présent document s'appliquent aux adjuvants utilisés dans un béton de consistance normale. Elles peuvent ne pas être applicables aux adjuvants destinés à d'autres types de béton tels que des bétons demi-secs et à consistance terre humide.
Les dispositions qui régissent l'utilisation pratique des adjuvants dans la production de béton, telles que les exigences relatives à la composition, au malaxage, aux conditions de mise en œuvre, à la cure, etc., du béton adjuvanté, ne sont pas traitées par le présent document.
