Abstract

Reinforced concrete structures have constantly become more safe and durable over the past century and the materials properties have improved tremendously, but the design and construction method have not changed much over time. Concrete structures face a series of challenges like a new degree of freedom for architecture, sustainability, health, increased productivity and a better integration to BIM models. 3D Concrete printing has the potential to meet these demands, although it is not clear yet which type of structures will benefit most from this additive type of manufacturing. However, in order to explore the benefits, the first task of research is to make the print process robust. This is needed since the load bearing capacity of a structure depends on the design and the printing strategy. Besides, the issue of a lack of reinforcing steel must be solved to ensure safe structures, for example by developing new and ductile types of concrete.
