2023 United Kingdom reinforced autoclaved aerated concrete crisis information
Building material
The 2023 United Kingdom reinforced autoclaved aerated concrete crisis relates to increased safety concerns over reinforced autoclaved aerated concrete, commonly used historically in roofing and wall construction within the public sector, having gained popularity in the mid-1950s as a cheaper and more lightweight alternative to conventional reinforced concrete.
Structural issues involving RAAC began surfacing publicly in the United Kingdom in the 1990s. Concerns were amplified in 2023 following reports of an earlier roofing collapse at a British primary school, which fell without warning in 2018. The material is still present in the UK in public buildings such as schools and hospitals. The material's nature makes it difficult to identify these issues before collapse, leading to the Department for Education issuing emergency closures to a number of schools due to the risk to pupils.
