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).
