Abstract

3D printed concrete (3DPC) as an emerging technology can promote the revolution of the conventional construction industry towards digitalization and automation. However, the shrinkage and sustainability issues of 3DPC, posed by the lack of coarse aggregate and high content of cement, are gradually coming to light and become a barrier in front of 3DPC development and application. Biochar has a significant potential to overcome multiple challenges for 3DPC. In this chapter, a comprehensive review was conducted to present the state-of-the-art development of low carbon 3DPC by using biochar as a carbon sequestrator. Biochar shows comprehensive effectiveness in enhancing 3DPC in terms of sustainability, volume stability, printability, mechanical performance and durability. Advancing biochar-enhanced low carbon 3DPC has the potential to comprehensively address the current challenges of 3DPC technology and decarbonize the construction industry.
