Reinforced autoclaved aerated concrete (RAAC) is a form of lightweight concrete sometimes referred to as panels. It was used primarily in the roof planks of some public buildings built between the mid-1950s and mid-1990s. Today, as can be seen in the press, it is a significantly topical subject. Kieran Browne of Fairhurst will give an overview of RAAC to the Aberdeen Association of Civil Engineers. This covers the history of the manufacture and use of RAAC as well as the maintenance and management of buildings with RAAC elements.
