Abstract
Reinforced autoclaved aerated concrete (RAAC) panels are widely used in mainland Europe. A new European Standard covering prefabricated RAAC components is about to be published, so it is timely to examine this form of construction. Describes: Circumstances where excessive in-service deflections and cracking have raised. concerns about the performance of RAAC roof panels designed before 1980, Laboratory testing used to evaluate the performance of RAAC roof panels recovered from a housing development and a school after some 20 years of service, Some mechanisms that potentially influence the observed in-service behaviours, The development and principal aspects of new design guidance for RAAC panels contained in prEN 12602, and The medium-duration testing completed in 2000 of some aspects of the performance of RAAC panels fabricated to the new design guidance. Does not apply to beam-and-block floors or walls that contain autoclaved aerated concrete (AAC) blocks in their construction, nor to any other AAC components.
