Reinforced autoclaved aerated concrete - or Raac - used in buildings between the 1950s to 1990s, is posing a threat, leading to the evacuation of 299 council properties in Aberdeen.
Raac, once seen as a lightweight alternative to traditional concrete, has now become a safety risk, necessitating the evacuation of various structures and prompting urgent actions by authorities to relocate tenants to safer accommodations.
