DTU on the benefits of exploring 3DCP in academics
Thomas Juul Andersen, the team leader at the Concrete Centre at Danish Technological Institute, points out: “In many places, it is not concrete that is used at all, but rather a mortar-like material. Unfortunately, typically it has a bigger carbon footprint than concrete. The development of new concrete solutions with lower cement content, for example, is therefore key to ensuring that 3D concrete printing becomes a climate-friendly solution. This is one of the things we are exploring in the N3XTCON research project.
3D concrete printing has great potential to reduce material consumption in concrete construction. This is because it is an additive solution—i.e., only the material to be used is added. For example, if you want to print a column, you don’t have to print a solid column. You might be able to make do with a hollow column.”
