Lime Kiln Dust Lime kiln dust (LKD) is physically similar to cement kiln dust, but chemically quite different. ... Such moisture conditioning will, however, cause full or partial hydration of the available free lime in the dust that may necessitate the later addition of a commercial hydrated lime to improve early strength development.

When lime is used, the soil is remixed and compacted 48 hours after the lime is applied. Cement kiln dust, on the other hand, gets rid of extra step, as the initial mixing and compacting is enough to stabilize the material sufficiently (Miller and Zaman, 2000). Cement is often used for soil stabilization in transportation construc-

In the UK, 1.2 million tonnes of lime was produced in 2019 (MPA, 2021). The main waste generated from the manufacturing of lime is an extremely fine-particle kiln dust, collected by dust control systems and extracted during the calcination process, with an average particle size less than 30 microns (Miller and Callaghan, 2004).
