3.2 Results of unconfined compressive strength tests of untreated and treated Barika CL soil with hydrated lime
UCS tests were performed on the Barika CL soil samples treated with hydrated lime. The treated samples carried out at various percentages of hydrated lime as shown in Table 4. The UCS of hydrated lime-treated samples develops rapidly with the hydrated lime percentage increase until the optimum hydrated lime content is reached. The soil samples in this study exhibit a rapid initial increase in the UCS with the addition of hydrated lime. The added optimum percentage of the hydrated lime to the natural soil sample further increased its UCS values (from 174.231 kN/m2 to 960.85 kN/m2). In comparison, similar results have been observed by various researchers who studied soils UCS properties such as Elhassan (2006).
