Soil is one of the most important engineering materials. So to work with soils, there is a need to have proper knowledge about their properties and factors which affect their behavior. The geotechnical properties of a soil such as its plasticity, grain size distribution, compressibility, and shear strength can be evaluated by proper laboratory testing. Soils containing large quantity of clay and silt are the most burdensome to the engineer. These material exhibit marked changes in physical properties with a change in water contents. A hard, dry clay, for example, may be suitable as a foundation for heavy load so long as it remains dry but may become unstable when gets wet, whereas many of the fine soils shrink on drying and expand on wetting which may adversely affect structures founded/constructed upon them. The present review study encourages the utilization of fines as a good engineering material. In this regard, it is necessary to replace the soil with fine admixtures in a fixed proportion, to get an optimum percentage of fine admixture which gives the Maximum Dry Density (MDD) and maximum California Bearing Ratio (CBR) value. This review study shows the results obtained from experimental results by various researchers on the effects of different types of fine admixtures on MDD and CBR values of soil. This review study concentrates on the performance of soil by replacing it with some percentage of fines. From the review, it has been observed that the optimum percentage replacement of fines in soil is around 30%.
