Sunny Bank Primary SchoolSt Columba’s Catholic Primary School, WallsendElmstead Primary SchoolRAAC is a lightweight, precast, cellular concrete building material made from quartz sand, calcined gypsum, lime, portland cement, water and aluminum powder.
Its lighter weight is achieved by using chemicals to create bubbles within it. A cross-section of a slab of RAAC looks similar in texture to an Aero chocolate bar.RAAC was used in roof, floor and wall construction due to being lighter in weight, reducing the load placed on supporting structures and foundations.
It also has good fire resistance properties without needing plastering and fire does not cause spalls, which is when fragments get broken off. Not all RAAC is dangerous by nature. It is still manufactured and installed all over the world and can be an appropriate construction material if properly designed, manufactured, installed, and maintained.RAAC started being used predominantly in public sector roof construction in the UK and parts of Europe in the 1950s and continued to be used until the 90s, but the material has been found to have structural issues that means it begins to deteriorate after 40 or 50 years.
