Reinforced aerated autoclaved concrete planks found on pitched roof of 1990s hospital building
A building constructed in the early 1990s has been found to contain reinforced aerated autoclaved concrete (RAAC) planks. This date is important since it is much later than the previously thought last significant use of RAAC in buildings in the UK and potentially affects the scope of buildings that could require screening for RAAC problems.
