Abstract:
This paper examines existing regulations, standards and guidelines in the field of exposed concrete and evaluates their transferability to concrete 3D printing, as there are currently no clearly defined requirements and specifications for concrete 3D printing. Building on this, a systematic examination of analogue and digital methods for recording surface qualities that can be used to assess concrete 3D printing is carried out. Some of these methods are then tested in practice in laboratory experiments to verify their suitability. Despite a predominantly qualitative evaluation of the resulting findings, the insights provide valuable approaches. Based on the theoretical and practical findings, ideas, recommendations and suggestions for the development of guidelines for the evaluation of additively manufactured concrete components were put forward, which can serve as starting points for further research.
