Striatus: the first-of-its-kind 3D Concrete Printed bridge

19 July 2021

Striatus, the first-of-its-kind 3D Concrete Printed bridge, has been unveiled in Venice in July 2021. This innovative project is designed by Block Research Group and Zaha Hadid Architects, in collaboration with incremental3D and made possible by Holcim. Striatus establishes a new language for concrete that is digital, environmentally advanced and circular by design.

 
 

Concrete at its best

The product of the best minds in their fields, Striatus demonstrates the infinite possibilities of 3D Concrete Printing to enable the creation of breakthrough infrastructure projects that are more sustainable, faster to build and cost-effective, with no compromise on aesthetics and experience.

Its digital and circular design uses concrete at its best: the footbridge holds together solely through compression with no reinforcements, applying computational design and 3D printing, for minimal material use and maximum strength.

All of Striatus’ components are designed to be infinitely disassembled and reused. The concrete blocks can be easily recycled, with limited energy and cost. The recycling process is simple and cost-efficient as no materials sorting is needed, due to the absence of reinforcements, glue or binders.

A blueprint for the future

Striatus is a complex structure made possible by a specific, custom-made ink, from Holcim’s TectorPrint range, developed by its 3D Concrete Printing research team. It sets a blueprint to build for the future using advanced technologies from computational design to 3D Concrete Printing. The next generation of inks can include Holcim’s green building solutions, from its ECOPact green concrete to its ECOPlanet green cement, including recycled construction and demolition waste. When it comes to building progress, the possibilities are endless.

The bridge is now open to the public in the Marinaressa Gardens during the Venice Architecture Biennale until November 2021.
