Item Low-Carbon 3D Printed Concrete: A General Review of the Technology and Method(2023-11-28) Soutus, JoaquinAbstract— During the last decades, there has been an increase in interest in news about technologies and application methods to turn concrete into a less polluting material. 3-D Printed Concrete technology is an innovation in this direction. The main purpose of this paper is to address the pollution issue in construction in general and in the concrete industry in particular. To achieve this aim, this paper is divided into three sections. The first section, the construction industry and concrete contamination is explained. The second section introduces 3D Printed Concrete technologies as a possible solution to the contamination issue, describing its composition, properties and elaboration process. Finally, the last section delves into the main economic, technological and environmental benefits of this technology. It is expected that this work can motivate the incorporation of new building technologies in the construction industry to address the contamination issue and contribute to environmental improvement.
