RAAC is basically a lighter-weight type of concrete, used to construct roofs, faculties, schools and different buildings from the Nineteen Fifties till the mid-Nineties.

But consultants worry that the fabric has now reached the tip of its shelf life and is liable to break down.

What is Reinforced Autoclaved Aerated Concrete?

Reinforced Autoclaved Aerated Concrete – handily shortened to RAAC – is basically a light-weight type of concrete.

It was used to construct roofs, faculties, schools and different buildings from the Nineteen Fifties till the mid-Nineties, in line with GOV.UK.

In comparability to conventional concrete, RAAC is weaker. It is made in factories utilizing fantastic mixture, with chemical compounds to create gasoline bubbles and warmth.

Both the fabric properties and structural behaviour differs considerably from conventional bolstered concrete.

In 2019, the Standing Committee on Structural Safety highlighted the numerous danger of failure of RAAC planks.

Three years later in 2022, the Office of Government Property despatched a security briefing discover to all property leaders, saying that “RAAC is now life-expired and liable to collapse”.

Chris Goodier, professor of building engineering and supplies at Loughborough University, stated: “It is RAAC from the Nineteen Fifties, 60s and 70s that’s of important concern, particularly if it has not been adequately maintained.

“RAAC examples have been found with bearings (supports) which aren’t big enough, and RAAC with the steel reinforcement in the wrong place, both of which can have structural implications.”

More faculties might be requested to close school rooms sooner or later, in line with ministers.

But the issue might be far wider than simply faculties, consultants say, with different buildings susceptible to “sudden and catastrophic collapse” if RAAC isn’t eliminated.

Chris Goodier, professor of building engineering and supplies at Loughborough University, stated the “scale of the problem is much bigger than schools”.
