Flow production of variable curved modules for thin-walled concrete shell structures. Thin concrete shells allow to achieve considerable material savings. However, the traditional manufacturing methods, which are based on concrete casting into formwork, are uneconomical from today‘s perspective. The modular approach can make shell construction more cost-effective, especially when producing shell modules with a high degree of automation. The ongoing “Adaptive Concrete Diamond Construction (ACDC) and beyond” project aims to develop an approach for fully automated fabrication of concrete shell modules of variable geometries. The project pays special attention to the reinforcement of the modules, which is accomplished by means of automatically laid carbon yarns. The contours of the modules are 3D-printed using Strain-Hardening Cementitious Composite (SHCC). This article presents the results already achieved in the project and also provides an overview of the ongoing work, which includes the production of non-planar modules, the implementation of post-processing techniques, and improving the sustainability of the new technology.
