Reinforced autoclaved aerated concrete (RAAC) is a form of lightweight concrete sometimes referred to as panels. It was used primarily in roof planks of some public buildings built between the mid-1950s and mid-1990s.

 

Why was this study group formed?

Following failures in reinforced autoclaved aerated concrete (RAAC) planks/panels, SCOSS issued an alert along with reports of failures to CROSS. This led to the Institution setting up this study group to provide a place for information and guidance on RAAC. You do not need to be a member of the Institution in order to join the study group - it is open to all.
