Stabilization of Soil using Chemical Additives

Searching for the best soil stabilizers to overcome the problem occurs by the clayey soils and sandy soils are still being the main concern, not only to achieve the required soil engineering properties but also by considering the cost and the effect to the environment. This research work presents the efficiency of sodium based alkaline activators as an additive in improving the engineering characteristics of cohesive and cohesion less soil. Investigations have been done in order to evaluate the effectiveness as soil stabilizer which involved the use of sodium hydroxide as chemical additive and concentrations of 1,2,4,8 molar were used. These materials were discussed in this paper and their effectiveness for stabilizing the soil were observed from the obtained results only in terms of strength and shear parameters like cohesion and angle of friction by conducting unconfined compressive test, California bearing test and direct shear test. The strengths of soil and their shear parameters were significantly increased with the use of sodium hydroxide as chemical additive and supposed they have the potential as effective soil stabilizers in field application.
