This thesis addresses the environmental challenge of managing excavated soil from urban infrastructure expansion. It develops a rapid and cost-effective method for measuring kaolinite, a clay mineral, in soil. The research explores recycling this soil as a component in high-quality cement, showing that soil with high kaolinite content can produce mortars as strong as or stronger than traditional cement. It also investigates the use of nano-calcined soil in improving cement properties and enhancing hydrophobic characteristics. This work promotes sustainable construction practices, reduces landfill waste, and supports a circular economy in the construction industry.
