BS EN 12269-1:2000

This standard BS EN 12269-1:2000 Determination of the bond behaviour between reinforcing steel and autoclaved aerated concrete by the "beam test" is classified in these ICS categories:

• 77.140.15 Steels for reinforcement of concrete
• 91.100.30 Concrete and concrete products
• 91.080.40 Concrete structures

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.
Measurement of tensile force in reinforcement at point of flexural failure in a specially prepared composite specimen.
