Sustainable nanotechnology-based stabilised soil

RoadCem (RC) is a nanotechnology additive containing synthetic zeolites and alkali earth metals. It stabilizes soil by partially replacing cementitious materials, aiming to reduce OPC usage by 50% with RC and GGBS. Lab tests show significant strength improvement in 7 days with RC, reducing swelling to 0% after 28 days. RC’s microstructure enhances cementation, with GGBS more effective than PFA in improving engineering properties. These findings offer promising solutions for reducing carbon footprint through OPC replacement.
