Sustainable Fire-Spalling-Resistant Concrete (SusFire)
Fire-induced spalling of concrete experienced by constructed facilities such as tunnels, buildings and bridges has been shown to cause catastrophic failure, and to lead to huge economic costs and potential loss of life. However, despite the consequences, fire-induced spalling remains one of the least well understood aspects of concrete behaviour. This project is funded by EPSRC aiming at developing an improved understanding of fire-induced spalling of modern high-performance concrete, and finding a sustainable spalling-mitigation solution by using fibres recovered from end-of-life tyres. To achieve this, four key objectives will be focused on:
- Develop a better understanding of fire-induced spalling and the spalling-mitigation mechanism of polymer fibres;
- Explore the potential of tyre fibres for preventing fire-induced spalling of high-performance concrete;
- Contribute to the standardisation of fire-spalling characterisation testing;
- Build a high-quality database for future research.
