The escalating pace of urbanization and the consequent demand for infrastructure development have given rise to a growing environmental concern – the generation of vast quantities of industrial waste. Among these waste materials, granite powder waste originating from stone processing units has emerged as a major challenge due to its detrimental impact on soil and water resources. Conventional disposal methods have contributed to soil degradation and environmental contamination, necessitating the search for sustainable alternatives for waste management. In this context, the utilization of red soil blended with granite powder waste presents a promising avenue for sustainable construction practices. This study delves into the nano-level characterization of this composite material and investigates its potential applications. Advanced characterization techniques, particularly scanning electron microscopy (SEM) and energy-dispersive X-ray analysis (EDX), were used to analyze the behavior of red soil mixed with different percentages of granite powder waste. The results highlight the mix with 30% granite powder waste as a particularly noteworthy composition, showcasing superior interlocking properties. The microstructure analysis at the nanoscale revealed the formation of clusters, leading to enhanced cohesion between particles and improved interlocking behavior. These findings demonstrate the potential of this soil- waste composite for sustainable soil improvement and geotechnical applications in construction. By understanding the nano-level interactions between red soil and granite powder waste, this study paves the way for innovative and environmentally conscious approaches to soil stabilization, promoting the efficient utilization of waste materials in construction projects. The research concludes with insights into future directions, focusing on long-term stability studies and potential environmental impacts. The application of nano- additives in soil stabilization opens up new possibilities for sustainable development and resource efficiency.
