The panelling is designed for economically challenged communities in South Africa. This collaboration aims to enhance construction efficiency and sustainability.
Combining 3D Concrete Printing and Geopolymer Concrete
The institutions plan to merge 3D concrete printing (3DCP) with Geopolymer Concrete (GPC) technology, a cement-less alternative to conventional concrete. This initiative is funded by The Royal Society and led by University of Sheffield academics Behzad Nematollahi, a lecturer in concrete technology, and Mehdi Chougan, a research associate in 3D concrete printing.
Reducing Waste and Carbon Emissions
The newly developed system utilises 3D concrete printing to minimise waste and accelerate construction. By incorporating geopolymer concrete technology, the process has the potential to achieve an 80% reduction in carbon emissions.
Advancing Sustainable and Affordable Housing
Nematollahi, project lead, said: “The groundbreaking nature of this project lies in its ability to tackle both challenges simultaneously by combining 3DCP and GPC technologies. While there are other universities in the UK that are conducting research on 3DCP using conventional cement-based materials, our work specifically targets the 3D printing of GPC, which sets us apart. This innovative approach not only reduces the carbon footprint of construction materials but also aims to lower costs, making it more accessible for applications such as affordable housing.”
