Abstract: Soil is play key role in construction industry as the structure are supported on soil. If the bearing capacity of the soilis not adequate then it may lead to fail of structure. Generally the failure is observed in expansive soil like black cotton soilwhich shows high swelling and shrinkage properties in contact with water. Mainly this property of swelling and shrinkage isdue to presence of mineral known as Montmorillonite. In order to remove this defect, it is vital to improve the properties of soilusing different additives. This method of bringing improvement in expansive soil is known as stabilization of soil. The mainobjective of stabilization is to improve bearings capacity of expansive soil. It is technique which improvises one or more soilindices by mechanical, cementing and chemical use. Many research has been conducted for stabilization of soil by usingcementing, chemical materials. The study done by various researchers have -shown lime and fly ash as key ingredient forstabilization of soil. This materials easy accessible and eco-friendly in nature. This paper attempt to give a synoptic review onvarious researches made on stabilization of soil using lime and fly ash.KEYWORDS: Soil, Stabilization, lime, fly-ash, black cotton soil.
