No RAAC found at Imperial (yet), says College
At least 16 UK universities have closed or partially closed areas containing RAAC.
Imperial says it has conducted initial inspections and has found no evidence of reinforced autoclaved aerated concrete (RAAC) at any College-owned or -operated buildings. “We will continue to conduct surveys and will take expert advice if potential RAAC is identified,” said the College.
RAAC is a type of concrete which was used in construction between the 1950s and 1990s. It is cheaper and lighter than standard concrete, but has a lifetime of around 30 years, and is prone to structural failure.
The Health and Safety Executive says RAAC is now beyond its lifespan and may ‘collapse with little or no notice.’ RAAC caused a stir over the summer after the UK government identified more than 100 schools where it had been used, and ordered them to shut temporarily.
At least 16 UK universities have closed or partially closed areas containing RAAC.
