Admixtures for concrete, mortar and grout - Test methods - Part 11: Determination of air void characteristics in hardened concrete

This European Standard describes a test method for determination of the air- void structure in a hardened concrete sample which contains entrained air. The air-void structure is described by means of the following parameters, which are defined in clause 3.  i) Total air content, ii) Specific surface of air void system, iii) Spacing factor, iv) Air-void size distribution, v) Micro air content.

Zusatzmittel für Beton, Mörtel und Einpressmörtel -Prüfverfahren - Teil 11: Bestimmung von Luftporenkennwerten in Festbeton

Dieses Dokument beschreibt ein Prüfverfahren zur Bestimmung des Luftporengefüges in einer Festbetonprobe, die luftporenbildende Zusatzmittel enthält. Das Luftporengefüge wird durch die folgenden Kenngrößen beschrieben, die in Abschnitt 3 näher definiert sind:
i)   gesamter Luftporengehalt;
ii)   spezifische Oberfläche eingeführter Luftporen;
iii)   Abstandsfaktor;
iv)   Porengrößenverteilung;
v)   Gehalt an Mikroluftporen.
Das beschriebene Verfahren ist ausschließlich für Probekörper aus Beton geeignet, dessen ursprüngliches Mischungsverhältnis genauestens bekannt ist, wobei der Probekörper für dieses Mischungsverhältnis repräsentativ ist. Dies ist im Allgemeinen nur bei im Labor hergestelltem Beton der Fall.

Adjuvants pour bétons, mortiers et coulis - Méthodes d'essai -Partie 11: Détermination des caractéristiques des vides d'air dans le béton durci

La présente Norme européenne décrit une méthode d�essai permettant de déterminer la structure des vides
d�air dans un échantillon de béton durci contenant des adjuvants entraîneurs d�air. Cette structure est décrite
au moyen des paramètres suivants, définis dans l�Article 3.
i) Teneur totale en air
ii) Surface spécifique des vides d�air
iii) Facteur d�espacement
iv) Distribution dimensionnelle des vides d�air
v) Teneur en microvides d�air
La méthode décrite ne s�applique qu�aux éprouvettes de béton durci dont on connaît avec précision la
composition, l�éprouvette étant représentative des proportions du mélange. En général, c�est uniquement le
cas du béton fabriqué en laboratoire.
