Lime Kiln Dust, a.k.a LKD, is a byproduct created when manufacturing Quicklime. When limestone is naturally heated, it produces gas with dust. The dust that is screened out is called Lime Kiln Dust. LKD, has little beneficial use, and is mostly disposed of into landfills. The site work industry uses LKD as a stabilizing agent to dry poor soils.
Lime Kiln Dust LIME KILN DUST. Specifications for Road Stabilization. For either high calcium or dolomitic hydrated lime, a minimum of 95% total oxide content (CaO + MgO) on a non-volatile basis is required. Carbon Dioxide (5 7% maximum, depending upon where sampled. Particle Size 85% passing #200 mesh sieve. NOTE:
Quicklime and lime kiln dust can also be used to dry wet soils at construction sites, reducing downtime and providing an improved working surface. The application of lime can significantly improve the engineering properties of soil. There are essentially two forms of improvement: soil modification and soil stabilization.
