Abstract

Clayey soils are problematic due to the reactions of their minerals, which gives them an exhibition of shrink-swell properties. The shrink-swell property obtains clayey soils as inappropriate material for direct utilisation in construction. In underdeveloped nations due to the remarkable development in road infrastructure, soil stabilisation has become the most efficient solution in construction industries. To make these soils more workable for construction, various methods (mechanical, chemical) and materials have been used. Cement, Lime, fly ash, and ground granulated blast furnace slag (GGBS) has usually used us stabiliser for developing the engineering properties of soil. The main focus of this review paper is on the utilisation of GGBS by-product and lime to enhance the geotechnical properties of the clayey soil. Experimental results of different tests like strength, microstructure, and compaction of various stabilizers and their percentages are evaluated and discussed. Lime and GGBS as local natural and industrial sources implied for chemical stabilisation. However, the reduction of waste material and its usage in construction has become an area of potential and promise.
