Experimental Investigation of Low-Carbon 3D Printed Concrete (2023-12)¶

The construction industry is currently experiencing significant change due to key advances in building information modeling The construction industry is currently experiencing significant change due to key advances in building information modeling (BIM), digital design and construction automation. These are each exerting intense pressure on traditional technologies, and an (BIM), digital design and construction automation. These are each exerting intense pressure on traditional technologies, and an example of this can be seen in 3D concrete printing. This is a rapidly developing technique that can potentially accelerate example of this can be seen in 3D concrete printing. This is a rapidly developing technique that can potentially accelerate construction times and improve efficiency. There are however major challenges associated with printing materials, as the majority construction times and improve efficiency. There are however major challenges associated with printing materials, as the majority of the research to date has focused on the use of traditional cements with high embodied carbon. This paper reports on the design of the research to date has focused on the use of traditional cements with high embodied carbon. This paper reports on the design of concrete printing mixtures using secondary cementitious materials, and show that it is feasible to develop printing concretes in of concrete printing mixture a more sustainable manner.
