What is it about?
This paper presents how synthetic fibre reinforcement can be used in real concrete structures instead of traditional steel reinforcement. Small plastic fibres are mixed directly into the concrete, improving its ductility and crack control while simplifying construction. The study shows practical applications such as tram track slabs, tunnel segments, and industrial floors, and demonstrates how these structures can be designed and verified using advanced numerical simulations and full-scale tests. The results highlight that synthetic fibre reinforced concrete can enable faster construction, reduced labour, and lower environmental impact compared with conventional reinforcement.

Why is it important?
Synthetic fibre reinforcement offers a practical alternative to traditional steel reinforcement in many concrete structures. By mixing fibres directly into the concrete, construction becomes faster and simpler, since placing and tying steel bars can often be reduced or even eliminated. This approach can also significantly reduce the environmental impact of construction, as synthetic fibres typically produce much lower CO₂ emissions than conventional steel reinforcement and can even be made from recycled plastics. As a result, fibre-reinforced concrete can help create more sustainable, durable, and efficient infrastructure.
Perspectives
In the future, reducing the environmental impact of concrete structures should not focus only on materials, but also on how we design them. While using alternative materials such as synthetic fibres already lowers CO₂ emissions, significant additional savings can be achieved by improving design methods and structural modelling. More advanced calculation approaches allow engineers to understand the real behaviour of fibre-reinforced concrete more accurately, which can reduce unnecessary material use. By combining innovative materials with smarter design methods, the construction industry can make meaningful progress toward more sustainable infrastructure.
