Experts warn that offices, court houses, hospitals, and factories containing Raac could be at risk of collapse.
Pupils from Corpus Christi Catholic School, Brixton arrive at St Martin’s in the Field Girls’ School in London, as they are relocated after their school was affected with sub standard reinforced autoclaved aerated concrete
However, other buildings are believed to contain Raac, with experts warning that offices, court houses, hospitals, and factories could be at risk of collapse.Raac is made up of two parts, aerated autoclaved concrete, and a steel reinforcement. The aerated autoclaved concrete is made by adding aluminium into a lime or cement based concrete mix.The steel reinforcement is coated with a latex or cement mix before the concrete is then cast around it.
A report by the Collaborative Reporting for Safer Structures published in April 2020 urged its members to check as a “matter of urgency” whether their buildings contained the material.
