CPC concrete slabs are based on the technology of “carbon pre-stressed concrete,” which originated from a long-term research project conducted by the Zurich University of Applied Sciences Winterthur (ZHAW) and Silidur AG, Andelfingen. These panels are reinforced with thin, pre-stressed carbon strands, allowing them to be three to four times thinner and lighter while maintaining the same load-bearing capacity as traditional reinforced slabs.
CPC’s innovative approach to concrete panel production reduces material usage by 75% and minimizes the carbon footprint of concrete production. ArchDaily interviewed Professor Josef Kurath from the Department of Architecture Design and Civil Engineering at the Zurich University of Applied Sciences (ZHAW), who collaborated with CPC Construction in developing these concrete panels. We discussed his perspectives on decarbonizing architecture, the inspiration behind the development of CPC panels, a comparison with traditional concrete, and the potential for scalability and accessibility in the future.
