Effect of Ground Nut Shell Powder on Soil Stabilization By IJISRT

Abstract

Various varieties of soil may be found across the world. The engineering features of soil are the most significant consideration in any building development. Construction on expanding soil is the most essential difficulty that civil engineers encounter. The expansive soil has typically undesired engineering properties, such as poor shear strength, plasticity, and compressibility; it expands when wet and shrinks when dry. Its characteristics can be enhanced with appropriate stabilizing procedures. Black cotton covers around 15% of the soil in India. Crops produced on black cotton soil include pea nuts, cotton, wheat, jowar, linseed, tobacco, castor, sunflower, and millets. In comparison, the peanut industry generates millions of tons of garbage. Nowadays, a key issue is "How to benefit from the industrial waste product." Soil stabilization is performed in order to improve the engineering qualities of the soil. The rising expense of typical stabilizing chemicals, along with the need to economically utilize industrial and agricultural waste for positive engineering reasons, prompted an inquiry into the stabilizing potential of groundnut shell powder (GSP) in expansive soil. This study looks at how to improve the geotechnical characteristics of expansive soil by performing various tests such as specific gravity, atterberg limit, compaction test, and California bearing ratio test to determine the properties of the untreated soil sample and then adding 5%, 7%, and 9% ground nut shell powder by weight of soil. In this phase, only untreated soil testing are conducted. After receiving treated and untreated soil results, compare the untreated black cotton soil results to various percentages of ground nut shell powder results to determine the optimum amount of ground nut shell powder necessary to increase the stability of black cotton soil.
