Soil stabilsation is one of the area which needs further research due to its importance both geotechnical and environmentally. Application of landfill materials and turn them into something worthwhile has been in attention of researchers. Lime Kiln Dust (LKD) is one of the materials which shows a potential of usage into soils. On other hand, Unconfined Compressive Strength (UCS) is also one of important tests in soil mechanics to represent characteristic of soil. Surely, in order to run UCS

... ing, compaction tests was conducted. The compaction values then utilized in the preparation of UCS samples. This study considers the effect of lime kiln dust on the UCS behavior of kaolinite-slag mixture. Compaction and UCS testing were conducted. The results showed that OMC was increased with increasing LKD in kaolinite-slag mixture and MDD was decreased with increasing in kiln dust. UCS also found to be with increasing in kiln dust. The results was support with different curing time (i.e. 7, 28, 90).
