Unions warn many school buildings ‘at risk of collapse’ News
Identifying problematic RAAC planks. The potential for sudden failure of reinforced autoclaved aerated concrete planks has been highlighted recently. So how can surveyors tell whether the material has been used for construction and identify the warning signs? Excessive deflections and transverse cracking were thought to be a key warning sign of.
The risks of Reinforced Autoclaved Aerated Concrete in building construction JMS Engineers
RAAC is a lightweight, 'bubbly' form of concrete that was commonly used in school and other buildings from the mid-1960s to the mid-1980s. RAAC is mainly found in roofs, although occasionally in floors and walls. RAAC is less strong than traditional concrete and there have been problems as a result, which could have significant consequences.
