Fire Protection of Concrete Tunnel Linings with Waste Tyre ...

The damages caused by fire-induced explosive spalling of concrete in tunnels can be tremendous; it could result in enormous economic cost and potential loss of human life. For this reason, the structural fire protection of concrete tunnel linings plays an important role in the tunnel design. Polypropylene fibres have been used in concrete to prevent explosive spalling of concrete exposed to fire.

Feb 19, 2019  To prevent fire spalling, modern codes recommend the use of small quantities (e.g. 2 kg/m3 as recommended by the Eurocodes) of polypropylene fibres in the concrete mix. This paper presents an experimental study investigating, the effect of cleaned recycled fibres extracted from end-of-life tyres on the explosive fire-induced spalling of concrete.

Different types of fibres are often used in concrete to prevent microcracking due to shrinkage, and polypropylene fibres are among the most often used ones. If not prevented, microcracks can lead to the development of larger cracks as drying shrinkage occurs, enabling penetration of aggressive substances from the environment and reducing durability of concrete structures.
