Portland Cement, Soil Cement, and Cement Slag can be used as chemical stabilizers for Soil Stabilization, Sub-grade Stabilization, Base Stabilization, or Full Depth Reclamation. Cement is one of the most versatile and readily available stabilizing materials in the nation, and plays a vital role in supporting our nations infrastructure responsibly.
Quicklime is cost effective, and available throughout the nation, making quicklime a great solution for drying wet soils. In the site work industry, quicklime is used for soil modification to dry and strengthen soils with a high plasticity rating such as fatty clay.
LIME KILN DUST (lkd)
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.
There are two types of fly ash, Class C and Class F. Class C has self-cementing properties and is used in the production of concrete as a substitute for Portland Cement, and as a chemical stabilizing & modifying agent to dry and/or strengthen poor soils. Class F has very little self-cementing properties, but can be combined with additives such as quicklime, hydrated lime, or cement (portland or hydraulic) to create cementitious compounds for the same purposes.
