Reusing large-format concrete elements
Slabs Under Tension
- Julien Pathé, Arnaud Paquier
Concrete floor slabs have the largest carbon footprint of all building elements. In the past, the material was lost irretrievably during demolition. A Swiss consortium is now cutting standard square slabs from buildings due for demolition and using them to manufacture prestressed segmental concrete elements with a higher structural performance than new reinforced concrete.
