Every year, millions of tonnes of excavated material are generated during tunnelling and underground construction projects. To date, most of this material has been disposed of in landfill sites without further use. The interdisciplinary research project Geo-BAB is investigating how such clay mineral-rich materials can be transformed into a low-CO2 alternative to conventional cement through thermal treatment and chemical activation.
