Determination of the drying shrinkage of autoclaved aerated concrete

This Euopean Standard specifies a method for measuring the relative length changes due to drying (drying shrinkage) of autoclaved aerated concrete manufactured according to EN 771-4 or prEN 12602. The shrinkage characteristics determined according to this method are the following: The conventional reference value of drying shrinkage is the relative length change between two specified moisture contents. The total value of drying shrinkage is the relative length change due to drying from the saturated state until reaching constant length under specified climatic conditions. Other drying shrinkage values may be determined between other parameters to meet other specified national requirements.

Bestimmung des Schwindens von dampfgehärtetem Porenbeton

Diese Europäische Norm legt ein Verfahren fest zur Messung der relativen Längenänderungen infolge
Austrocknung (Trocknungsschwinden) von dampfgehärtetem Porenbeton, der nach EN 771-4 oder
prEN 12602 hergestellt wird. Die nach diesem Verfahren bestimmten Schwindkennwerte sind die folgenden:
Der konventionelle Referenzwert des Trocknungsschwindens ist die relative Längenänderung zwischen zwei
festgelegten Feuchtegehalten. Der Gesamtwert des Trocknungsschwindens ist die relative Längenänderung
infolge Austrocknung vom wassergesättigten Zustand bis zum Erreichen konstanter Länge unter festgelegten
klimatischen Bedingungen. Um anders festgelegte nationale Anforderungen zu erfüllen, dürfen auch andere
Kennwerte für das Trocknungsschwinden zwischen anderen Parametern bestimmt werden.

Détermination du retrait de séchage du béton cellulaire autoclavé

La présente Norme européenne spécifie une méthode de mesurage des variations relatives de longueur dues
au séchage (retrait de séchage) du béton cellulaire autoclavé fabriqué conformément à l’EN 771-4 ou
au prEN 12602. Les caractéristiques de retrait déterminées selon cette méthode sont les suivantes : la valeur
de référence conventionnelle du retrait de séchage est la variation relative de longueur entre deux teneurs en
humidité spécifiées. La valeur totale du retrait de séchage est la variation relative de longueur due à la
dessiccation entre l'état saturé et l'état correspondant à une longueur constante dans des conditions
ambiantes spécifiées. D'autres valeurs du retrait de séchage peuvent être déterminées entre d’autres
paramètres afin de satisfaire à d’autres exigences nationales spécifiées.
