A full list of schools in England affected by RAAC (reinforced autoclaved aerated concrete) has been released by the UK government.

It comes as over 100 schools and colleges have been told to close or partially shut by the Department for Education (DfE) due to RAAC concrete, only days before thousands of pupils were due to return for the new school year.

As of August 30, there are 147 schools with confirmed RAAC on site, with nine more investigated but none was found.

What is RAAC concrete?

RAAC) is a building material that is a lightweight form of concrete.

The Standing Committee on Structural Safety (SCOSS) has noted that: "Although called ‘concrete’, (RAAC) is very different from traditional concrete and, because of the way in which it was made, much weaker.

"RAAC was used in schools, colleges and other building construction from the 1950s until the mid-1990s.

“It may therefore be found in any school and college building (educational and ancillary) that was either built or modified in this time period."

Hospitals in England told to be ready to evacuate due to RAAC

Hospitals in England have been warned they must be ready to evacuate if buildings containing RAAC begin to show signs of structural failure.

A letter sent from NHS England to trust chiefs said 27 sites had previously been identified as having RAAC, with three of them having already eradicated the concrete.

The letter, from NHS England’s chief commercial officer Jacqui Rock and national director for emergency planning and incident response Dr Mike Prentice, called for trusts to make sure work to identify and manage RAAC had been properly carried out.

NHS chiefs have been told to have procedures to cope with the failure of the material, including for the “decant of patients and services”.

Managers in hospitals where RAAC has already been confirmed have been told to ensure that management plans to deal with it are “sufficiently robust and being implemented”.

But the letter added that plans for RAAC-related collapses also needed to be kept up to date.

NHS England said: “Effective management of RAAC significantly reduces associated risks; but does not completely eliminate them.

“Planning for RAAC failure, including the decant of patients and services where RAAC panels are present in clinical areas, is, therefore, part of business continuity planning for trusts where RAAC is known to be present, or is potentially present."
