Abstract

Driven by promising efficiency gains, 3D concrete printing is rapidly evolving. To facilitate the transfer of the findings into construction practice, it is recommended to develop concretes within the specifications of standards. It is shown, that limiting the fine particle content is a major challenge. A generalizable, numerically supported application of the particle size distribution according to andreasen and andersen is proposed as a solution. Its application in printing tests proves good extrudability and buildability of standard-compliant concrete with 16 mm largest grain size and a fine particle content of 500 kg/m 3.
