The partnership between Stahlton Bauteile and Zirkulit contributes to turning the vision of a recyclable concrete house into reality. In the EMPA NEST STEP2 unit, the partners use an innovative ribbed filigree slab featuring post-tensioning and optimized 3D geometry with the support of digital tools to create considerably lighter structures requiring less concrete and significantly saving on CO2. For the remaining required concrete, a formulation minimizing cement and maximising use of secondary materials has been developed further reducing the environmental impact.
