Air pollution, water body contamination, airborne particulate matter, land use issues, and the release of dangerous chemicals are just a few of the ecological and environmental issues that can arise from the growing volume of this trash and its inappropriate use. Therefore, handling and management of bottom ash are essential for reducing such potential hazards. By adding varying amounts of bottom ash to the soil, the current study seeks to enhance the consolidation properties of clayey-silt with sand soil. The impact of different percentages of bottom ash combined with soil is investigated in a lab experiment using a developed 3D consolidation device. Additionally, the amount of bottom ash variations on layered soil and the impact of various surcharge loads on the bottom ash treated soil are examined. The study’s conclusions demonstrate that the consolidation rate rises as the proportion of bottom ash in the soil advances, reaching its maximum rate when 40% bottom ash content is added. Increasing the amount of surcharge load significantly increases the consolidation rate. The condition having the highest percentage of bottom ash mixed in soil layers gives highest consolidation rate. The current study is advantageous because it minimizes and reuses bottom ash by using it to strengthen the weak soil present at the construction site while minimizing environmental impact.en-USBottom ash3D consolidationSurcharge loadsCo-efficient of consolidation (cv)Rate of consolidationConference Paper0
