Abstract
The first thin folded concrete prototypes produced with Smart Dynamic Casting (SDC) exposed numerous challenges concerning concrete. The SDC process is modelled to explain the increased difficulty to fabricate thin folded members compared to columns. Due to the smaller volume to surface ratio in formworks for thin folded structures the effect offriction is amplified and the process window narrows down. In order to compensate for this, retarded self-compacting mortar mix designs and acceleration strategies are investigated. Material testing results provide guidelines of how to achieve a uniform hardening rate over the course of an experiment, while preserving sufficient fluidity and dealing with variations in raw materials. For this, offline penetrometer tests are performed to evaluate material properties and online measurements are recorded to follow the strength evolution of the same mix processed with the experimental setup. In addition, the slipping criterion and the deformability of the concrete are tested in a 1:1 scale robotic experiment to evaluate the fabrication feasibility with the adapted mix. This unveils the potential to produce thin folded members for architectural applications.
