Testing fresh concrete - Part 3: Vebe test

This European Standard specifies a method for determining the consistency of fresh concrete by means of the Vebe time.
The test is suitable for specimens having a declared value of D of the coarsest fraction of aggregates actually used in the concrete (Dmax) not greater than 63 mm.
If the Vebe time is less than 5 s or more than 30 s, the concrete has a consistency for which the Vebe test is unsuitable.

Prüfung von Frischbeton - Teil 3: Vébé-Prüfung

Diese Europäische Norm legt ein Verfahren zur Bestimmung der Konsistenz von Frischbeton mit Hilfe der Vébé-Zeit fest.
Die Prüfung ist für Proben geeignet, deren deklarierter Wert D des Größtkorns der tatsächlich im Beton verwendeten Gesteinskörnungen (Dmax) nicht größer als 63 mm ist.
Wenn die Vébé-Zeit weniger als 5 s oder mehr als 30 s beträgt, hat der Beton eine Konsistenz, für die die Vébé-Prüfung nicht geeignet ist.

Essais pour béton - Partie 3 : Essai Vébé

La présente Norme européenne spécifie une méthode de détermination de la consistance du béton frais par l’essai Vébé.
L’essai est adapté aux échantillons ayant une valeur déclarée de D pour les plus gros granulats effectivement utilisés dans le béton (Dmax) inférieure ou égale à 63 mm.
Si le résultat à l’essai Vébé (temps Vébé) est inférieur à 5 s ou supérieur à 30 s, le béton présente une consistance qui ne peut être déterminée au moyen de l’essai Vébé.

Preskušanje svežega betona - 3. del: Vebe preskus

Ta evropski standard določa metodo za določanje konsistence svežega betona s pomočjo časa Vebe.
Preskus je primeren za primerke, pri katerih je deklarirana vrednost D najbolj grobega agregata, ki je dejansko uporabljen v betonu (Dmax), manjša od 63 mm.
Če je čas Vebe manj kot 5 s ali več kot 30 s, ima beton konsistenco, za katero preskus Vebe ni primeren.

This European Standard was approved by CEN on 29 April 2019.

CEN members are bound to comply with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this
European Standard the status of a national standard without any alteration. Up-to-date lists and bibliographical references
concerning such national standards may be obtained on application to the CEN-CENELEC Management Centre or to any CEN
member.

This European Standard exists in three official versions (English, French, German). A version in any other language made by
translation under the responsibility of a CEN member into its own language and notified to the CEN-CENELEC Management
Centre has the same status as the official versions.

1 Scope
This document specifies a method for determining the consistence of fresh concrete by means of the
Vebe time.
The test is suitable for specimens having a declared value of D of the coarsest fraction of aggregates
actually used in the concrete (D ) not greater than 63 mm.
max
If the Vebe time is less than 5 s or more than 30 s, the concrete has a consistence for which the Vebe test
is unsuitable.
2 Normative references

constitutes requirements of this document. For dated references, only the edition cited applies. For
undated references, the latest edition of the referenced document (including any amendments) applies.

4 Principle
The fresh concrete is compacted into a slump cone. The cone is lifted clear of the concrete and a
transparent disc is swung over the top of the concrete and carefully lowered until it comes in contact
with the concrete. The slump of the concrete is recorded. The vibrating table is started and the time
taken for the lower surface of the transparent disc to be fully in contact with the grout (the Vebe time),
is measured.
