“…Additionally, the Food and Agriculture Organization reports that 54 million tonnes of groundnuts were produced in 2021, with China and India leading the way [14]. Groundnut shells (GS) account for 20-25% of dried peanut pods by weight, making their utilisation important [31,36,44]. They have high lignin content, making them resistant to bio-degradation under normal environmental conditions [3,29,36].…”

Utilizing waste materials to improve soil properties can result in cost savings and environmental benefits. This study aims to determine the effect of adding agricultural wastes like rice husk ash (RHA), rice husk (RH), and groundnut shells (GS) to clayey sands from Mysore district, India. The study focused on the undrained strength, permeability and volume change behaviour of soils mixed with RHA, RH and GS. The soil samples were mixed with varying amounts of RHA (5%, 10%, 15%, and 20% by weight) and RH-GS (1%, 2%, 3%, 4%, and 5% by weight) and cured for 1, 7, 14 and 21 days. These blended specimens were then used to determine the maximum dry density (MDD), optimum moisture content (OMC) and unconfined compressive strength (UCS). The soil mixture containing 5% RHA and 4% (RH + GS) yielded optimal results in the UCS test. Further tests, including unconsolidated undrained (UU) triaxial, permeability and consolidation tests, were conducted on the parent soil and the soil composite with 5% RHA and 4%(RH + GS). From the undrained test, the strength increased for the soil admixture, with a reduction in the cohesion and an increment in the friction angle, compared to that of the parent soil. The experimental results also showed improvement in the permeability and consolidation characteristics of the blended soil.

“…They have high lignin content, making them resistant to bio-degradation under normal environmental conditions [3,29,36]. The hydroxyl groups present in GS contribute to its absorption capacity [29,44]. The bulk density of the unprocessed GS ranges from 100-155 kg/m 3 [34].…”
