A potentially dangerous building material linked to cases of school roofs suddenly collapsing may have been used in the construction of up to 15 council buildings in Edinburgh, it has emerged.
Concerns over Reinforced Autoclaved Aerated Concrete (RAAC) have sparked an investigation by the city council - but it would not confirm if any of the buildings currently being surveyed are educational facilities.
The bubbly, lightweight concrete was commonly used in the construction of roofs and walls in the UK from the 1950s to 80s but is now believed to pose a "risk to life" after incidents of school ceilings caving in.
