Precast concrete products - Test methods for glassfibre reinforced concrete
This document specifies test methods for identifying the performance of a glassfibre reinforced concrete (GRC) composition in terms of bending strength, water absorption, dry density and dimensional variations.
These methods can be used for type testing or for the evaluation of the uniformity of the production process. They can be used on GRC coupons prepared as described in this document, or on samples cut out of GRC products.
NOTE A test to assess the influence of time on the mechanical properties (i.e. LOP and MOR) is described for information in Annex C. Other methods can be found in scientific literature.
Betonfertigteile - Prüfverfahren für Glassfaserbeton
Dieses Dokument legt Prüfverfahren für die Ermittlung der Leistungsfähigkeit einer Glasfaserbe
ton- (GFB)-Zusammensetzung hinsichtlich Biegefestigkeit, Wasseraufnahme, Trockenrohdichte und Maßänderungen fest.
Diese Verfahren können für Typprüfungen oder zur Beurteilung der Gleichmäßigkeit des Produktions- prozesses angewendet werden. Sie können an GFB-Probekörpern angewendet werden, die wie in diesem Dokument beschrieben hergestellt werden, oder an Proben, die aus GFB-Produkten ausgeschnitten werden.
Zudem wird in AnhangC auch eine zyklische Bewitterungs-Typprüfung beschrieben.
Produits préfabriqués en béton - Méthodes d'essai des composites ciment-verre
Le présent document spécifie des méthodes d’essai pour identifier les performances d’une formule de composite ciment-verre (CCV) en termes de résistance à la flexion, d’absorption d’eau, de masse volumique sèche et de variations dimensionnelles.
Ces méthodes peuvent être utilisées pour les essais de type ou pour l’évaluation de l’uniformité du procédé de fabrication. Elles peuvent être utilisées sur des coupons de CCV préparés comme décrit dans le présent document, ou sur des échantillons découpés dans des produits en CCV.
NOTE Un essai pour évaluer l'influence du temps sur les propriétés mécaniques (i.e. LOP et MOR) est aussi décrit à titre informatif dans l’Annexe C. D'autres méthodes peuvent être trouvées dans la littérature scientifique.
