Utilization of kiln dust in clay stabilization

Abstract EN

Kiln dust is a waste material produced in considerable quantities during the manufacture of portland cement.

This paper presents results of a testing program to explore the effect of kiln dust on plasticity, compaction and strength characteristics of clayey soils.

Results indicated a considerable decrease in plasticity and marked increase in compressive strengths as a result of the addition of kiln dust.

Also, kiln dust enhanced compressive strengths of cement-soil or lime-soil mixtures.
