Sustainable Construction for the Future
With the completion of the new bridge in Neuhofen an der Krems in 2024, a pioneering construction project has been realized. The uniqueness of this project lies in the use of carbon concrete, an innovative alternative to conventional reinforced concrete. The decision to use this material brings numerous advantages in terms of durability, sustainability, and resilience.
Technical Details of the Bridge
The bridge spans approximately 32.5 meters in length and has a width of about 3.50 meters. The carbon concrete slabs used are only 8 cm thick and are prestressed transversely as a three-span beam. The concrete quality is C35/45, ensuring high strength and durability. As reinforcement, solidian GRID Q95-CCE-38 was used in both the upper and lower layers, with the edges reinforced by the solidian GRID Form Q95-CCE-38 as U-profile.
Collaboration and Project Partners
This innovative bridge project was realized in collaboration with:
🟠Planning: ZT-Fritsch GmbH, Steyr
🟠Prefabrication of Concrete Elements: SFW Salzburger Fertigteilwerk GmbH, Bergheim
The bridge in Neuhofen an der Krems is an impressive example of the future of construction. With carbon concrete as a material, structures can be designed not only to be more resource-efficient but also more durable and low-maintenance. This highlights the relevance of innovative materials for a sustainable infrastructure.
The project was designed and executed in Austria in accordance with the German technical approval Z-1.6-308.

Why you should use carbon concrete for a bridge?
Carbon concrete has prevailed in this project over the originally planned GFRP bridge decking – and for good reasons:
🟠Higher Robustness: Carbon concrete is extremely resistant to environmental influences and mechanical stress.
🟠Economic Efficiency: Unlike conventional reinforced concrete, it does not corrode, significantly reducing maintenance costs.
🟠Sustainability: Since carbon concrete is lighter than reinforced concrete, the material quantity can be reduced, lowering the CO₂ footprint.
🟠Longer lifespan: The guaranteed lifespan of carbon concrete components according to Z-1.6-308 is 100 years.
