In some places soil may be weak which cannot resist the oncoming loads in such cases soil stabilization is needed, the clay often is weak has no stability in heavy loading. The study involves replacing a varying percentage of soil with quarry dust and introducing eggshell powder for enhancing the properties and obtained the optimum mix proportion. In this experimental study we use eggshell powder and quarry dust to enhance the properties of soil, the test were carried out using various percentages of quarry dust like 8%, 16%, 24% and 32% as soil replacement and where max density value gained eggshell powder is added with a percentage of variation 4%, 8%, 12%and 16% to the weight of soil. The most appropriate percentage of quarry dust replacement and eggshell powder addition for black cotton soil and red soil was determined, which can be used to stabilize these soils for construction purposes. This experimental study provides valuable information for researchers and engineers in the field of soil stabilization. The study was carried out through a series of laboratory tests, including sieve analysis Atterberg limits, compaction, unconfined compressive strength and California bearing ratio (CBR) tests. Key Words: Red soil, Black cotton soil, sieve analysis, atterberg limits, compaction, unconfined compressive Strength, California bearing ratio 1.0 INTRODUCTION:- Soil stabilization is the process of altering the properties of soil to improve its strength, Durability and resistance to deformation. It involves various techniques and methods that aim to enhance the soil's ability to support structures and withstand external forces such as traffic Loads, environmental changes, and natural disasters. The need for soil stabilization arises when the natural soil is not strong enough to support the intended use, such as building foundations, Roads, airports, and different infrastructure projects. Soil stabilization may be done with the aid of using adding different materials to the soil, such as cement, lime, fly ash, or chemical additives. The type of stabilizer used depends on the soil's characteristics, the desired engineering properties, and the project's requirements. There are various methods of soil stabilization, which can be broadly categorized into mechanical, chemical, and physical methods. Mechanical methods involve adding materials such as gravel, sand, or geo-textiles to the soil to improve its stability. Chemical methods involve the addition of substances such as lime, cement, or fly ash to the soil to alter its chemical and physical properties. Physical methods involve the use of techniques such as compaction, grouting, or freezing to improve the soil's strength and stability. Soil stabilization offers many benefits, including reducing construction costs, improving the performance of structures, and enhancing the safety and reliability of the infrastructure. It also minimizes the environmental impact by reducing the need for excavation and transportation of soil materials, which results in fewer greenhouse gas emissions and energy consumption. 2.0 OBJECTIVE OF THIS STUDY:- This study aims to investigate the effectiveness of using quarry dust and eggshell powder as stabilizers for black cotton soil and red soil. 3.0 LITERATURE REVIEW:- Lime stabilization: - In a study conducted by Mohammed et al. (2019) in Nigeria, varying percentages of lime (2%, 4%, 6%, and 8%) were added to black cotton soil. The study found that the addition of lime improved the soil's strength, with the highest strength achieved at 6% lime content. Bitumen stabilization:- In a study by Masu et al. (2020) in Nigeria, varying percentages of bitumen (2%, 4%, and 6%) had been introduced to black cotton soil. The study found that the addition of bitumen improved the soil's stability, with the highest stability achieved at 6% bitumen content.
