Abstracts: Growing urban developments have intensified the demand for housing and roads, resulting in densification of land use. As a result, structures have been constructed in agricultural areas that have been converted into residential colonies. These soils pose several problems to the structures. Construction of any infrastructure over weak/soft/expansive soil is highly typical on the geotechnical grounds, as the soil undergoes differential settlements, poor shear strength and high compressibility. In these aspects, improvement of soil has been observed by adopting various techniques like soil stabilization, adoption of reinforcement, etc. Generally, admixing technique in soil is an effective ground improvement technique because of its easy adaptability. In this project, various laboratory tests would be performed on the admixed soils, and the effect of the various admixtures on these soils would be analyzed. The admixtures chosen for the study would be Fly Ash, Plastic Waste, Red Soil, Iron Wares, Cement, Lime etc. and the combination of these with the different soils, at different percentages. The above study would give an insight to determine the impact on such admixed soils on engineering properties of soils such as permeability, compaction and shear strength etc., and how they improve the properties of the soils.
