Effect of Olivine Additive on the Shear Resistance of Fine-Grained Soils: A Sustainable Approach for Risk Mitigation and Environmental Impact Reduction

Increasing urbanization has also accelerated the potential risks of hazards arising from problematic soils. At this end, it becomes inevitable to apply soil improvement methods, which are most applicable and economical methods. strength clays, especially in undrained conditions where they exhibit low shear resistance, is essential for mitigating soil-induced hazards. This study aimed improve resistance clays with a waste material named olivine, rarely been used soils before. The samples prepared at different curing times was determined various confining pressures. Both olivine-added potassium hydroxide (KOH)-activated were tested same manner. It proven that olivine contribution alone not sufficient over time, higher obtained when activated KOH. treated only added grains, whereas KOH both grains chemical bonds up rate 521% case 20% being used. Morphological mineralogical analyses performed analyze formed after reaction. Stabilization substitutes sustainable method provides benefits such as reducing carbon dioxide emissions controlling waste.
