📰 York Castle Museum partially closed after #RAAC discovery
Surprised we haven't seen more headlines like these: #museums all over the country must be built out of the reinforced autoclaved aerated concrete (RAAC) they've discovered propping up the gallery ceilings in #York.
The concrete has a life-span of 30 years and we've been cheerily putting it in just about everything between the 1950s until the mid-90s. :yikes:
