An In-depth Comparative Study on the Efficacy of Solid Waste Additives for Enhancing Soil Stabilization in Cohesionless Soil: A Paradigm for Sustainable Engineering Practices

This research paper aims to conduct a comprehensive comparative analysis of various solid waste additives for soil stabilization, focusing on their efficacy in enhancing the engineering properties of cohesionless soils. The study will investigate the performance of different solid waste materials, such as fly ash, saw dust and nano-silica in stabilizing soils that lack cohesive properties. Through a series of laboratory-scale experiments and geotechnical testing, the research will evaluate the impact of each waste additive on critical soil parameters including grainsize analysis, Atterberg’s limit, compaction and shear strength characteristics. The investigation will also consider the environmental implications and economic feasibility of incorporating these waste additives, providing a holistic assessment of their suitability for sustainable soil stabilization practices. By presenting a comparative analysis, this research aims to offer valuable insights into the selection and optimization of waste additives for soil stabilization in cohesionless soils, facilitating informed decision-making for engineers and environmental practitioners engaged in sustainable construction projects and reduce the landfill load in the landfill site to help the environmental and circular economy.
