The education secretary has said that the “vast majority” of schools will not be affected by reinforced autoclaved aerated concrete (RAAC).<br /><br />RAAC is a potentially dangerous material as it can be prone to sudden collapse as it ages. It was used to construct schools, colleges and other buildings between the Fifties and mid-Seventies in the UK.<br /><br />There are over 22,000 schools and colleges in England and the vast majority of them are unaffected by RAAC”, Ms Keegan told the House of Commons.<br /><br />“We have been supporting schools and colleges to ensure that risks resulting from RAAC are being mitigated.”
