what is raac in schools

RAAC stands for reinforced autoclaved aerated concrete, which is a lightweight, bubbly form of concrete commonly used in construction between the 1950s and mid-1990s. It was used mostly in flat roofing, but also in floors and walls. Recently, there has been a safety risk associated with RAAC, as it has been found to be at risk of collapse. The government has published a list of 174 schools and colleges in England that have buildings with unsafe RAAC concrete. The danger of RAAC has led to the closure of some school buildings. The new guidance on RAAC in education settings provides information on how to identify RAAC, assess the risk, and manage the risk if RAAC is found.
