Lime is one of the most researched additives for soil stabilization. Due to their high silica (SiO2) content, pozzolans have also attracted significant attention from researchers in this field. Diatomite, a pozzolan with high silica content, is typically used with binders such as lime due to its lack of active calcium oxide (CaO). This study investigates the combined use of diatomite and lime for soil stabilization to address gaps in the literature. Eight specimens were prepared: four containing 6% lime and four without lime, with diatomite contents ranging from 0% to 20%. Consistency limit tests, compaction tests, and unconfined compressive strength tests were conducted. The results indicate that diatomite with lime significantly enhances soil strength and accelerates early strength gain. At 1 and 7 days, the highest strength was observed in the lime-amended specimen containing 20% diatomite. However, at 28 days, the lime-amended specimen with 5% diatomite achieved the highest strength. In contrast, diatomite had no significant effect on the strength of lime-free specimens. These findings demonstrate that the combination of diatomite and lime effectively improves soil properties and accelerates strength development.
