Construction of a hypar concrete shell using fabric and cable net formwork

This workshop was part of the Digital Tools-Parametric Design course at Chalmers University of Technology. The participants were students in the Architecture and Engineering program. The formwork was made during two days in December 2023, and the concrete casting was performed during one day in January 2024.
Workshop leaders were Emil Adies, Fredrik Boman, Erik Wigh and Chris Williams.
The theme of the workshop was based on the research performed at ETH
"Design process for prototype concrete shells using a hybrid cable-net and fabric formwork" by Veenendaal and Block block.arch.ethz.ch/brg/public...
Apart from the amazing students who were part of the workshop, we also want to thank those who have helped us with the planning and execution:
Lars Adiels, Arezou Babaahmadi, Sebastian Almfeldt, Philippe Block & Block Research Group, ETH Zurich, Anders Karlsson, Peter Bäckgren, Jacob Forsberg, Peter Lindblom, Tabita Nilsson, Oliveira Gonçalves, Emil Svedjer & Diederik Veenendaal.

That’s super cool! What was the mix design like?

Thanks! :) Do you mean the concrete mix? We used StoCrete R 40, which we got for free from our concrete lab since they no longer need it. The mix itself turned out great. It was not too slippery and not too dry. We could apply it even on the patches with the highest curvature without problems. We were lucky to get help from my dad, who is a master bricklayer, to get the right proportions of water into the mix.
