Expansive clay is a major source of undulations induced in any type of structures. Swelling of expansivesoils causes serious problems and produces harm to many structures. Many research organizations aredoing extensive work on waste materials concerning the viability and environmental suitability. Spentbleaching earth and misspend cement are waste derivatives from oil industry and cement warehouse. Toavoid dumping problem and storage problems, it is the best method technique applied in expansive soils.Attempts are made to investigate the stabilization process identified in unconfined compressive strength andtri-axial compressive strength.Stability of any structure depends on strength properties of underground soilon which it is constructed. Structures basically transfer all the loads come on itself directly to the ground. Ifthe underlying soil is not stable enough to support transferred loads then various types of failure occur suchas settlement of the structure, cracks and so on. To solve this issue, soil improvement is necessary because itnot only lowers the construction cost but also cuts the risk of any damage of structure later on. Numerousimprovement methods can be adopted to make ordinary soil stable enough to support the structural loads. Inthis research work a number of tests may conduct using both ordinary soil and stabilised soil. This thesisexplains the strength behavior of SBE treated black cotton soil reinforced with MC. The various percentage ofSBE as 5%, 10%, 15%, 20% and 25% was used to find out the optimum value of RBI Grade. MC has beenrandomly included into the SBE treated soil at four different percentages of MC content, i.e. 2%, 4%, 6%, 8%and 10%.
