Constructed at Holcim’s Innovation Hub, in Lyon, the Phoenix Bridge is a collaboration between Zaha Hadid Architects Computation and Design Group (ZHA CODE), Holcim, Block Research Group at ETH Zurich, and incremental3D.
The new ten-ton Phoenix design offers an evolution of the innovations seen in the previous Striatus bridge, the original blocks of which the team was able to recycle in the second iteration.
Demonstrating circular construction combined with 3D concrete printing offers significant carbon reductions, the Phoenix Bridge is the latest milestone by Holcim and its partners in their work to develop low-carbon structural solutions at every scale.
The bridge gains its structural strength from compression, which means that it needs no mortar or reinforcement, and the material required to make can be cut by about half.
The concrete blocks it is made from contain recycled materials and they can be disassembled and recycled, making the building process circular.
