An overview of traditional and non traditional stabilizer for soft soil

Abstract

Abstract Soft soil always deal with high compressibility, high water content, low shear strength and low permeability. All these challenges lead to soil failure such as excessive settlement, failure of sub structure which is lead to superstructure damage and many others failure. Hence, soil stabilization is one of the option in ground improvement technique by adding other stabilization agent either natural basis or chemical basis. This paper critically reviewed about advantages and disadvantages of chemical stabilizer namely traditional and non traditional. Also closely reviewed on polymer and lignosulfonate as soil stabilization agent in various type of soil. Reviewed and analysing of some references revealed that using non traditional stabilizer have more advantages than traditional stabilizer in term of engineering properties as well as chemical composition. Polymer and lignosulfonate also have their on specialties in order to corporate with various type of soil.
