Admixtures for concrete, mortar and grout - Part 2: Concrete admixtures - Definitions, requirements, conformity, marking and labelling
This European Standard specifies definitions and requirements for 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 standard 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 standard.
Zusatzmittel für Beton, Mörtel und Einpressmörtel - Teil 2: Betonzusatzmittel - Definitionen, Anforderungen, Konformität, Kennzeichnung und Beschriftung
Diese Europäische Norm legt Begriffe und Anforderungen für Zusatzmittel für Beton fest.
Sie gilt für Zusatzmittel für unbewehrten Beton, Stahl- und Spannbeton, die für Ort- und Transportbeton sowie
für Beton für Fertigteile verwendet werden.
Die Leistungsanforderungen nach dieser Norm 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.
Diese Norm gilt nicht für 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 dieser Norm.
Adjuvants pour bétons, mortier et coulis - Partie 2: Adjuvants pour béton - Définitions, exigences, conformité, marquage et étiquetage
La présente Norme européenne fixe les définitions et les exigences pour les adjuvants utilisés dans les bétons.
Elle s'applique aux adjuvants pour bétons non armés, armés et précontraints utilisés dans les bétons fabriqués sur chantier, prêts à l'emploi et préfabriqués.
Dans cette norme, les exigences de performance 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 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 la présente norme.

3 Terms and definitions
For the purposes of this document, the terms and definitions in EN 934-1:2008 and the following apply.
3.1 General definitions
3.1.1
performance
ability of an admixture to be effective in its intended use without detrimental effects
3.1.2
compliance dosage
dosage of an admixture, expressed in % by mass of cement, stated by the manufacturer which will meet the
requirements of this standard. The compliance dosage is within the recommended range of dosage
3.1.3
recommended range of dosage
dosages between limits expressed in % by mass of cement which the manufacturer recommends for the
product based on experience on site
NOTE The use of the recommended dosage does not imply that compliance with this standard will be met over the
whole range. Trial tests should be carried out with the materials to be used on site to find the dosage necessary to achieve
the required result.
3.1.4
maximum recommended dosage
upper limit of the recommended range of dosage
3.1.5
reference concrete and mortar
concrete and mortar as specified in EN 480-1 for testing admixtures for conformity with this standard
3.1.6
multifunction admixture
admixture which affects several properties of fresh and/or hardened concrete by performing more than one of
the main functions defined in 3.2.2 to 3.2.9
3.1.7
primary function
single function of a multifunction admixture designated by the manufacturer
3.1.8
secondary function
function of a multifunction admixture which is additional to the primary function
3.2 Specific definitions
3.2.1
admixtures for concrete
material added during the mixing process of concrete in a quantity not more than 5 % by mass of the cement
content of the concrete, to modify the properties of the mix in the fresh and /or hardened state
3.2.2
water reducing/plasticizing admixture
admixture which without affecting the consistence, permits a reduction in the water content of a given concrete
mix, or which, without affecting the water content increases the slump/flow or produces both effects
simultaneously
3.2.3
high range water reducing/superplasticizing admixture
admixture which, without affecting the consistence, permits a high reduction in the water content of a given
concrete mix, or which, without affecting the water content increases the slump/flow considerably, or produces
both effects simultaneously
3.2.4
water retaining admixture
admixture which reduces the loss of water by a reduction of bleeding
3.2.5
air entraining admixture
admixture which allows a controlled quantity of small, uniformly distributed air bubbles to be incorporated
during mixing which remain after hardening
3.2.6
set accelerating admixture
admixture which decreases the time to commencement of transition of the mix from the plastic to the rigid
state
3.2.7
hardening accelerating admixture
admixture which increases the rate of development of early strength in the concrete, with or without affecting
the setting time
3.2.8
set retarding admixture
admixture which extends the time to commencement of transition of the mix from the plastic to the rigid state
3.2.9
water resisting admixture
admixture which reduces the capillary absorption of hardened concrete
3.2.10
set retarding/water reducing/plasticizing admixture
admixture which produces the combined effects of a water reducing/plasticizing admixture (primary function)
and a set retarding admixture (secondary function)
