Improvement of subgrade properties using traditional additives such as lime and portland cement adds supplementary costs therefore using byproducts in this domain involves technical economic and environmental advantages cement kiln dust ckd is generated in huge quantities as a byproduct material in portland cement plants

If separated into its valuable components waste cement kiln dust could become a significant source of potassium and a raw material for making cement in 1982 the united states imported almost 1 million tons of potassium as k2o equivalent if all the potassium from cement kiln dust could be reclaimed potassium imports could be cut by 25 pct

Dust shuttling has been identified by the us environmental protection agency epa as a means of reducing mercury emissions this takes advantage of the significant internal mercury cycle within the system due to cement kiln operating temperatures and material flows cement kiln dust ckd naturally absorbs mercury

The product of the kiln operations is called clinker the clinkering reactions involve conversion of mixtures of calcium carbonate and silica and alumina bearing components to a mixture of special crystalline components capable of reacting with water to produce controlled setting and strength gain
