UK's Crumbling Concrete Crisis: Decades-Old RAAC Poses Safety Risks for Schools and Hospitals
-
RAAC is a type of concrete used from the 1950s-1980s that is now crumbling in many UK buildings like schools and hospitals.
-
RAAC has a lifespan of only about 30 years and is prone to collapse when wet, raising safety concerns.
-
Researchers raised concerns about RAAC's durability as early as the 1980s, but widespread action wasn't taken until recently.
-
Over 150 UK schools have been forced to close due to the presence of RAAC, prompting outrage over the government's slow response.
-
The government has pledged to rebuild 7 hospitals with RAAC and provide funding for schools to assess risks, but many say more action is still needed.
