Muroom soil found locally finds application in majorly all the sites of construction. The soil in its natural state is stiff, hard and presents a very durable sub-surface for the overlying pavements or any other structure. However, the soil loses a lot of its strength when soaked or in damp and wet conditions. The cost of procurement and transportation also poses serious economic problems when the soil is required in large quantity. The review paper focuses on the studies conducted earlier on stabilization of existing soil using Fly-ash and Gypsum. The reuse of Fly-Ash which is a major industrial waste for strengthening and improving the properties of the soil would solve the major problems of disposal of Fly-Ash and the degrading air quality index due to Fly-Ash fumes. The use of Fly-Ash would make construction as well as soil stabilization more effective in terms of economy and the ease with which the materials can be procured. Gypsum majorly obtained from mining also finds use in soil stabilization. Various other forms and by-products of Gypsum such as Phosphogypsum, Marine-gypsum, FGD (Flue Gas Desulphurization) gypsum, Citro-gypsum etc. find major use in a wide variety of Industries as well as in Geo-Technical operations for the improvement in soil properties. The paper discuses about the tests and conclusions laid down by the works done previously on the process of soil stabilization using Fly-Ash and Gypsum. It also sheds some light on how muroom can be partially replaced by other industrial wastes as the cost of procurement of muroom is very high as compared to that of Gypsum which is easily available and cheap. The Pozzolanic actions of Fly-Ash, as well as the improvement in Soil Permeability due to Gypsum addition are the areas of interest in particular.
