An element people are forgetting is what happened after 1945. There was a huge expansion of primary and especially secondary schooling, thanks to the post-war government's enlightened educational policies. Not only was there a need for new school buildings - they had to be larger than in the past, and RAAC, which was cheaper than standard concrete and was being touted in Scandinavia, where it was developed, was a tempting material both for governments and builders. One imagines that after six years of war a projected 30-year lifespan for a building material seemed at that time like an eternity.
