Holcim, a pioneer in 3D concrete printing, celebrates the completion of the 'Phoenix' bridge, a testament to sustainable infrastructure advancements. This revolutionary project, developed in partnership with Block Research Group at ETH Zurich, Zaha Hadid Architects Computation and Design Group, and incremental3D, builds upon the success of the award-winning 'Striatus' bridge showcased at the 2021 Venice Biennale of Architecture.

Constructed with 10 metric tons of recycled materials, including aggregates from the original Striatus blocks, Phoenix epitomizes Holcim's commitment to sustainable practices. The company introduced a specialized concrete ink, reducing Phoenix's CO2 footprint by 40% compared to its predecessor and lowering the structure's overall carbon impact by 25%.

Holcim's collaboration resulted in the development of a custom concrete ink, incorporating recycled construction materials and 100% recycled ECOPlanet cement using the ECOCycle circular technology. This innovation, combined with computational design and 3D printing, enabled a remarkable 50% reduction in material usage while maintaining performance. The bridge's design, capable of enduring compression without reinforcement, facilitates easy disassembly and recycling of its blocks.

Edelio Bermejo, Head of Global R&D at Holcim, expresses pride in unveiling Phoenix, emphasizing the project's contribution to demonstrating feasible circular and low-carbon infrastructure. The initiative stands as a testament to Holcim's commitment to decarbonize construction for a sustainable future.

The creation of Phoenix involved contributions from various entities, including AMODIS for design and control, DEKRA for testing and certification, Groupe Noel for metal manufacturing, and Bürgin Creations for assembly.

According to Shajay Bhooshan, Head of the Computation and Design Group at Zaha Hadid Architects, Phoenix showcases an evolution in design-to-construction technologies. The bridge's improvements in design tools, structural enhancements, and tighter integration with 3D printing parameters signify a technological milestone from its predecessor, Striatus.

Johannes Megens, Co-founder of incremental3D, commends the project's progression and reduced carbon footprint, affirming their excitement for future endeavors aligned with the sustainability spirit showcased by Phoenix.

Philippe Block, Co-Director of the Block Research Group at ETH Zurich, highlights the bridge's design principles, emphasizing a circular approach to concrete construction that enables easy recycling and reassembly, furthering sustainable practices.

Conclusion:

Holcim's collaborative effort in creating the Phoenix bridge stands as a paradigm of sustainable infrastructure development. The project, leveraging recycled materials, circular concrete technology, and innovative design, marks a significant leap in 3D concrete printing, setting new standards for environmentally conscious construction practices.
