Abstract - Black cotton soils are good for agriculture but it
stabilised. The characteristics of the soil will vary depending on its location, physical characteristics, and other factors. Several ways are available to stabilise the soil, but they should first be tested in a lab setting with actual soil before being used in actual field settings.
has low bearing capacity than other soils and prefer for the construction of high-story buildings and highways. The black cotton soil has high swelling properties in the rainy season and has high shrinkage in the property in the summer season. Soil stabilization is having different methods and material that improves physical soil characteristics such as an increased bearing capacity of soil and increased shear resistance can be done by adding waster material, jute fiber, fly ash, lime, cement, and adding different admixture for compacting for the subgrade stabilization of the building, high storage, heavy bridges, railway track, and highway Hence in this paper, we conducted soil stabilization using cement, lime, and sand on black cotton soil for the improvement in the properties of black cotton soil as stability, reduced in reduced shrinkage by using cement slurry, sand, and lime in varying percentages. (Soil + 10% Sand +5% Lime + 5% Cement, Soil + 15% Sand +5% Lime + 5% Cement, Soil + 20% Sand +5% Lime + 5% Cement) Laboratory tests were undertaken to study the strength characteristics of back cotton soil with cement, sand, and lime. Key Words: Black cotton soil, Stabilization, Cement slurry, increasing stability.
1. INTRODUCTION Black cotton soil covers 20% of India's land area, mostly in Gujarat, Maharashtra, M.P., South U.P., and portions of Karnataka, A.P., and Tamilnadu. Soils have high consolidation settling and are particularly compressive when they are saturated. The high swelling characteristic of these soils causes harm to the structure. Black cotton soil loses a lot of its bearing ability during the rainy season as a result of water filling up the cracks and crevices. This soil contracts during the dry season, causing uneven building settlement, cracks in walls and floors, etc.

The long-term physical and chemical change of soil will improve its physical properties, which can improve shear and unconfined compressive strength and permanently lower the soil's permeability to water. Soil stabilisation should be cost-effective.
Enhancing the strength or carrying capacity of soil through controlled compaction, proportioning, and/or the addition of the appropriate admixtures or stabilisers is known as soil stabilisation. In order to boost strength and durability under design usage conditions and to extend the design life of the engineering project, soil, a naturally occurring substance, is
