Abstract - The vast majority of soils on Earth are composed
conducted on BCS to ascertain its MDD, OMC, LL, PL, Specific Gravity, and CBR values. In order to execute the aforementioned test, stabilising agents like IOTs are added at various percentages, including 10%, 15%, and 20%. The field-collected soil sample is dried in the sun or in the open air. With the aid of the proper tool, the clods are shattered to speed drying. The soil sample had the organic material, such as tree roots and bark fragments, removed. The soil sample is dried in an oven for 24 hours at a temperature between 110°C and 150°C.
mostly of active clay minerals. Clayey soils are characterised by poor lasting ability and high settlement. Geotechnical engineers must consider a wide range of technical difficulties while planning a building's foundation. Engineers can gain from improving the soil by adding fibres, Iron Ore Tailings, and other elements. With a rise of 0.20% PPF to 0.60% and a constant 10% dose of Iron Ore Tailings by the weight of soil, numerous tests are conducted on black cotton soil. The final strength level is reached at 0.4% PPF and a constant 10% Iron Ore Tailing dosage.
The MDD of the plain soil is raised by the addition of iron ore tailings in percentages of 10, 15, and 20%..
Key Words: Iron Ore Tailings, PPF (Polypropylene Fibre), stabilization.

Saurabh. Sanjay Deshpande and M.M. Puranik (2018)[4] The goal of this study was to examine how adding fly ash and polypropylene fibre to black cotton soil affected its various engineering qualities. As the percentage of polypropylene grew, the maximum dry density fell and the ideal moisture content rose. As the amount of polypropylene grew, so did the soil's unconfined compressive strength. It was discovered that 15% and 1.5%, respectively, of fly ash and polypropylene fibre, were the ideal amounts.
Introduction
The stability of the base is significantly influenced by the soil around the structure. It is crucial to stabilise the soil in order to get the ideal soil properties. Iron Ore Tailings soil stabilisation is made possible by adding polypropylene fibre and improving the strength. Strong foundations are essential for any construction that is load-based and needs a certain amount of structural strength to hold it up against failure. Iron Ore Tailings and randomly distributed polypropylene fibres from waste materials are used in this project to stabilise the soil. With the addition of PPF and Iron Ore Tailings, OMC decreases and MDD rises. The swelling of the soil decreases together with the L.L. and P.L.

LITERATURE REVIEW
Mohammed SaqibQadeer and Vinod Kumar Sonthwal (2021)[3] conducted there explorations into expansive earth. Clayey soils have increased settling and poor lasting ability. Geotechnical engineers have many challenges while designing foundations. Research studies benefit from being able to focus on better ways to address those problems by incorporating lime, fibres, etc. into the soil. Numerous studies are conducted on BC soil with an increased PPF of 0.25 to 0.75% and a constant 4% lime by soil weight. Finally, a steady lime dose of 4% and 0.50% PPF yield the maximal strength.
