Mix design concepts for 3D printable concrete: A review

Over the past decade, 3D concrete printing has shown enormous application potential for the industry. The new technology poses specific requirements on 3D printable concrete (3DPC), especially on its rheological properties in the fresh state. The current codes and standards for conventional concrete construction are not applicable for guiding the mix design of 3DPC. Developing robust mix-design guidelines of printable concrete while considering...
