Processing of Set on Demand Solutions for Digital Fabrication in Architecture

Digital fabrication with concrete holds potential to rationalize the production of large-scale mass-customized shapes in architecture. However, these digital technologies have manifold requirements for concrete compared to ordinary casting due to the relatively long production time combined with the need for fast strength build-up after placing. Thus, first, a large retarded batch of concrete is prepared to provide extended open time for fabrication. Then, the retarded concrete is accelerated on demand in small increments over the course of the experiment.
