Stabilizing heavy metal-contaminated soil with solid waste-based materials is a sustainable approach. This study synthesized a coal bottom ash-based geopolymer and coir for the treatment of Cd- and Pb-contaminated soil. The results demonstrated that adding 10% geopolymer stabilized over 95% of Cd and Pb in contaminated soil, with the maximum compressive strength of soil reaching 634 kPa after curing. Geochemical model simulations revealed that Pb and Cd primarily converted to precipitated mineral forms (Cd4(OH)6SO4, Pb4(OH)6SO4, Litharge, and larnakite) when the system pH exceeded 5. From a me...
