Abstract The research investigated the influence of green ash on the engineering properties of fine-particle soils, with a focus on their suitability in construction and electronic industries. The soil underwent treatment with plantain peel ash (PPA) at varying concentrations of 2, 4, 6, 8, and 10% by mass of the dried soil, and was followed by a curing period of 21 days. Thereafter, the California Bearing Ratio (CBR), free swell index (FSI), dielectric constant (ε’), dielectric loss (ε”), and relaxation time (τ) values were measured following ASTM-approved guidelines. The results revealed that the PPA had substantial influence on the soil CBR and FSI parameters. The soil CBR increased from 4.39 to 16.62%, while the FSI declined from 15.27 to 8.77%, as the PPA quantity increased linearly from 0 to 10%. Regarding the soil dielectric parameters, the results depicted that the ε’, ε” and τ increased unevenly from 4.27 to 7.11, 1.01 to 1.85, and 4.18 to 4.6, respectively, when the concentration of the PPA was increased evenly from 0 to 10%. The improvements noted due to the PPA presence in the soil, impacting both its geotechnical characteristics and specific dielectric properties, indicate the potential for utilizing PPA in the production of eco-friendly electronic components.
