3D concrete printing processes are the subject of very rapidly growing research activities around the world. The approaches for 3D concrete printing mainly focus on the production of unreinforced concrete elements. In contrast, the proposed solutions for the integration of reinforcement are still rudimentary. At the TU Dresden, CONPrint3D® has developed from a research idea to an implementable technology through intensive interdisciplinary research activities in the last 5 years. The current state of development allows printing of unreinforced concrete elements on a 1: 1 scale under laboratory conditions using the worldwide unique full-wall printing process. In the next development step, the application scenarios are extended to elements that are subject to higher loads. This requires integration of reinforcement for 3D-printed concrete elements. Since steel is by far the most widely used reinforcement material in concrete construction, the proposed project focuses on this type of reinforcement.
The aim of the project is to produce reinforced concrete walls using CONPrint3D®. Thus, the areas of application of the CONPrint3D® technology can be expanded from masonry construction to reinforced concrete elements. Particular attention is paid to economic efficiency and process reliability for use directly on the construction site as well as general compliance with current standards and regulations. At the end of the project, an integrator of reinforcement is to be constructed and implemented on a laboratory scale. Also, reinforced wall elements are 3D printed as demonstrators.
The research project is funded by Zukunft Bau Forschungsförderung des Bundesinstitutes für Bau-, Stadt- und Raumforschung in the Bundesamt für Bauwesen und Raumordnung.
