Fibres for concrete - Part 2: Polymer fibres - Definition, specifications and conformity

This document specifies requirements for polymer fibres for structural or non-structural use in concrete, mortar and grout. It covers fibres intended for use in all types of concrete and mortar, including sprayed concrete, flooring, precast, in-situ and repair concretes.
Provisions governing the application of polymer fibres in the production of fibre reinforced concrete or mortar elements, i. e. requirements concerning fibre content, structural design, mixing, placing, etc. of concrete including polymer fibres are not part of this standard.
NOTE   Structural use of fibres is where the addition of fibres is designed to contribute to the load bearing capacity of a concrete or mortar element, see 3.18.

Fasern für Beton - Teil 2: Polymerfasern - Begriffe, Festlegungen und Konformität

Dieses Dokument legt Anforderungen an Polymerfasern für Beton, Mörtel und Einpressmörtel für tragende und nicht tragende Zwecke fest. Es gilt für Fasern zur Verwendung in allen Arten von Beton und Mörtel einschließlich Spritzbeton, Beton für Betonböden und Fertigbetonteile, Ortbeton und Beton für Instand¬setzungsarbeiten.
Diese Norm enthält keine Vorschriften für die Anwendung von Polymerfasern in der Herstellung von faser¬verstärkten Beton  oder Mörtelbauteilen, d. h. keine Anforderungen hinsichtlich Faseranteil, Baukonstruk¬tion, Mischung, Anordnung usw. von Beton einschließlich Polymerfasern.
ANMERKUNG   Bei der Verwendung von Fasern für tragende Zwecke tragen die zugegebenen Fasern zur Tragfähig¬keit eines Beton  oder Mörtelbauteils bei, siehe 3.18.

Fibres pour béton - Partie 2: Fibres polymère - Définition, spécifications et conformité

Le présent document spécifie les exigences relatives aux fibres de polymère pour une utilisation structurelle ou non structurelle dans le béton, le mortier ou le coulis. Il traite des fibres destinées à être utilisées dans tous les types de béton et de mortier, y compris le béton projeté, le béton pour dallage, le béton pour préfabrication, le béton coulé en place et le béton de réparation.
Les dispositions régissant l’application de fibres de polymère dans la production d’éléments en béton ou en mortier renforcé par des fibres, c’est-à-dire les exigences concernant la teneur en fibres, le calcul statique, le malaxage, le coulage, etc. du béton comprenant des fibres de polymère, ne font pas partie de la présente norme.
NOTE   L’utilisation des fibres est dite structurelle si l’ajout de fibres est conçu pour contribuer à la capacité portante d’un élément en béton ou en mortier, voir 3.18.

European foreword
This document (prEN 14889-2:2018) has been prepared by Technical Committee CEN/TC 104
“Concrete and related products”, the secretariat of which is held by DIN.
This document is currently submitted to the CEN Enquiry.
This document will supersede EN 14889-2:2006.
This document has been prepared under a standardization request given to CEN by the European
Commission and the European Free Trade Association, and supports essential requirements of
EU Directive(s).
For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this
document.
This standard comprises two parts:
— Part 1 dealing with steel fibres for concrete;
— Part 2 dealing with polymer fibres for mortar and concrete.
Not all fibre characteristics that may be relevant to the performance of a fibre concrete, structural or
non-structural, such as early age effects, creep and chemical attack, have been addressed in this
standard due to the difficulties of formulating meaningful and reproducible standardised test methods.
1 Scope
This document specifies requirements for polymer fibres for structural or non-structural use in
concrete, mortar and grout. It covers fibres intended for use in all types of concrete and mortar,
including sprayed concrete, flooring, precast, in-situ and repair concretes.
Provisions governing the application of polymer fibres in the production of fibre reinforced concrete or
mortar elements, i. e. requirements concerning fibre content, structural design, mixing, placing, etc. of
concrete including polymer fibres are not part of this standard.
NOTE Structural use of fibres is where the addition of fibres is designed to contribute to the load bearing
capacity of a concrete or mortar element, see 3.18.
