Project description
3D printing for construction with excavated soils
Climate change has pushed many important sectors, including the construction industry, into looking for greener alternatives (less energy-intensive materials and less environmentally impactful technologies). Earth-building technologies have met with greater interest in recent years, but high labour costs and time requirements have hindered their development. Further excavated soils from infrastructure demolition could provide for cheaper and greener materials. The Marie Skłodowska-Curie Actions RePrintCLAY project aims to utilise these ideas to develop an efficient 3D printing combination and strategy utilising excavated soils with trace amounts of additives. This idea will be studied. If all goes according to plan, this could build cheaper and cleaner construction.
Objective
Modern construction materials are energy-intensive, and therefore, the construction industry can reduce emissions by developing alternate building materials and adopting innovative construction technologies. There is an upsurge of interest in earth building technologies, but there are associated limitations such as labour cost and construction time. On the other hand, the construction and demolition of infrastructure produce a surplus of excavated soils that ends up at landfills. In this scenario, processing these soil wastes locally and integrating them in buildings as earth-based construction materials using 3D printing technology is an ideal solution. Therefore, the project assesses the technical feasibility of reusing the excavated soil, for producing earth-based composites, with sustainable additive combinations for enabling 3D printing. An industrial by-product such as Ground Granulated Blast-furnace Slag (GGBS) is proposed as an additive with other inorganic admixtures in trace quantities for treating the soil. The rheological parameters, the time-dependent green strength development characteristics and the long-term compressive strength characteristics of the soil treated with additives will be studied. The microstructure of the hardened earth mixes will be used for explaining their mechanical performance. The project will deliver promising earth mix combinations that are environmentally friendly, printable and made from by-products resources and excavation soil wastes. The outcomes of the project will be instrumental in delivering the decarbonization goals of the construction industry. This project is supported by the excellent research environment provided by the host, Dr Perrot at UBS and Prof. Habert at ETH Zrich, with state-of-the-art facilities for research development, testing and training. This project offers unique scientific opportunities that enable the candidate to return to mainstream research and excel in future career perspectives.
