摘要：

The annual disposal of rice husk ash (RHA) and fly ash (FA) from agro-based and power plants are substantial causing pollution, land acquisition for waste disposal, diseases related to respiratory and other negative impacts. The incorporation of rice-husk ash (RHA) and Fly Ash (FA) with lime (L) as a soil additive is a recent development, and its impact on soil mechanical qualities has been thoroughly investigated in this experimental study. This in-depth experimental study aims to investigate the impact of consistency and compatibility of RHA and FA at varying rates from 10 to 20% with 5% increments on clayey soil. About 18 samples of varying proportion were prepared and subjected to experimental evaluation. The experimental procedures in soil stabilization involve combining lime and raw soil with varying percentages of FA (10%, 15%, and 20%) and RHA (10%, 15%, and 20%). With 2% lime mixed with 20% RHA & 15% FA proportion, the highest value of OMC and MBD was recorded. This also implies the application of RHA and FA reduced the maximum dry bulk density (MBD) while increasing the optimum water content (OWC). The consistency limit of this proportion was showing decreased plasticity because the soil's flocculated structure was filled with fine ash particles, filling up all the spaces. © The Author(s), under exclusive licence to Springer Nature Switzerland AG 2024.
