M/BC/CEN/92/14 - CPD: Ext. & int. walls

This European Standard specifies a method of determining the bond behaviour between reinforcing bars and autoclaved aerated concrete (AAC) in prefabricated reinforced components according to prEN 12602. The test method is conceived to obtain values for the short term bond strength, tbm, with different combinations of concrete type, bar shape and corrosion protection system.

This European standard specifies the procedure for the determination of the longitudinal long-term strains (creep strains) of test specimens taken from prefabricated components of autoclaved aerated concrete (AAC)     or lightweight aggregate concrete with open structure (LAC) according to EN 1520 due to a constant compression stress sustained over a long period of time.

Diese Europäische Norm legt ein Verfahren zur Bestimmung des Langzeit-Verbundverhaltens zwischen Bewehrungsstäben und dampfgehärtetem Porenbeton (AAC) in vorgefertigten bewehrten Bauteilen nach prEN 12602 fest. Das Prüfverfahren ist dafür gedacht, Werte der Langzeit-Verbundfestigkeit fb,l zu gewinnen, die in einer abschließenden Kurzzeitprüfung bestimmt werden. Die Prüfung wird für verschiedene Kombinationen von AAC-Art, Stabform und Korrosionsschutzsystemen durchgeführt.
