What is RAAC Concrete & Why Is A RAAC Survey Essential?
Reinforced Autoclaved Aerated Concrete, commonly known as RAAC, is a type of precast concrete that gained popularity in the 20th century for its lightweight and thermal insulation properties. Favoured for its ease of installation and cost-effectiveness, RAAC became a staple in various construction projects.
RAAC is composed of fine aggregates, cement, and an expanding agent that gives it a porous structure. This unique composition not only makes it lighter than traditional concrete but also provides excellent insulation. However, over the years, concerns regarding its durability and structural integrity have risen.
This underlines the need for comprehensive RAAC surveys to ensure the safety and longevity of buildings that utilise this material.
What Buildings Have RAAC Concrete
RAAC concrete found its way into a myriad of building types, particularly in the industrial, educational, and healthcare sectors. Common in buildings erected from the 1960s to the 1980s in the UK, RAAC was utilised in roof planks and wall panels.
Schools, hospitals, and cold storage facilities are among the structures most frequently built with RAAC. Given the widespread use of this material, regular RAAC surveys are essential to assess its current condition and to plan for any necessary maintenance or reinforcement.
RAAC Concrete Issues
The primary concern with RAAC concrete stems from its susceptibility to moisture ingress and carbonation. This leads to a reduction in its alkalinity. This process can significantly compromise the embedded steel reinforcements, making them prone to corrosion.
As a result, structures with RAAC can face serious safety risks, including potential structural failures. The ageing of RAAC concrete, along with its hidden vulnerabilities, underscores the importance of conducting regular RAAC surveys.
These surveys are crucial in detecting early signs of deterioration and implementing timely interventions to mitigate risks.
How to Identify RAAC Concrete
Identifying RAAC concrete in existing buildings can be challenging without professional expertise. Buildings constructed between 1960 and 1980 are more likely to contain RAAC. Visual indicators include a ribbed pattern on the underside of roof panels. There is also, generally, a lighter feel of the material compared to traditional concrete.
However, the most reliable method of identification is through a professional RAAC survey. During such a survey, experts use various techniques to analyse the material composition.
We’ll assess the condition of the concrete, ensuring accurate identification and evaluation.
