: In this investigation explore the possibilities of utilizing materials to improve the engineering behavior of problematic soil. Soil stabilization in alluvial soil is necessary, as their volume changes due to variation in water content. Generally, it expands throughout the rainy season owing to the addition of intake of water or shrink in water. In this investigation the type of admixture namely marble powder and guar gum for stabilization is selected to study the effects of same on the problematic soil. MP and GG were mixed by partial replacement of soil by weight in 5%, 10%, 15%, 20% and 0.5%, 1%, 1.5%, 2%, respectively. The key properties of natural soil were extracted and several tests, such as specific gravity, Atterberg limits, grain size analysis, unconfined compression strength, standard proctor test and Scanning electron microscopy test were performed on soil samples prepared with different percentages of MP and GG. An unconfined compression strength test was used to obtain desired comprehensive strengths following 7, 14, 28 days of curing time. Shear strength of different sample is compared to find optimum proportion of additives. It is observed that 20% of marble powder and 1.5% of guar gum provide maximum strength.
