Researchers at the Structural Engineering Laboratory of the Swiss Federal Laboratories for Materials Science and Technology (Empa<\/a>) are working on the development of concrete elements produced using a 3D printer. According to a press release<\/a>, the building elements are stable without traditional steel reinforcement and are virtually cement-free. The material is designed to store carbon dioxide as it cures.<\/p>\n

The research is being carried out as part of the European CARBCOMN project (Carbon-negative compression dominant structures for decarbonised and de-constructable concrete buildings). Alongside Empa, researchers from the Swiss Federal Institute of Technology Zurich (ETH<\/a>) and the Empa spin-off re-fer<\/a> in Seewen, as well as other European partners, are involved in the development.<\/p>\n

The material for 3D printing is derived from recycled industrial waste, such as steel slag. Geometrically optimised shapes are produced using a special process. Iron-based shape memory alloys (Fe-SMA) from re-fer are used as reinforcement. To cure this concrete, carbon dioxide is injected into a combustion chamber, where it chemically bonds with the concrete mixture. “We are combining unique expertise here – 3D printing, structural performance<\/span> and our speciality: iron-based shape memory alloys,” Empa researcher Moslem Shahverdi is quoted as saying in the press release. “On the one hand, we use digital manufacturing methods to build in a resource-efficient manner. On the other hand, we are replacing conventional cement with binders that have a lower carbon footprint.” The concrete components are also designed so that they can be dismantled after use and reused elsewhere.<\/p>\n

Launched in 2024, the four-year project is funded under Horizon Europe<\/a> and brings together eleven leading research institutions and architectural firms from across Europe. According to the press release, these include Ghent University<\/a>, Darmstadt Technical University<\/a>, the University of Patras<\/a> in Greece, as well as Zaha Hadid Architects<\/a> from London, Mario Cucinella Architects<\/a> from Bologna, and the companies Tesis <\/a>from Penta di Fisciano in Italy, orbix<\/a> from Genk, and incremental 3D<\/a> from Innsbruck.<\/p>\n","protected":false},"excerpt":{"rendered":"
