ABSTRACT:
For the disposal of salt-containing dusts of incinerator plants, with addition of water the salt-containing dusts are intensively mixed with other waste materials, such as ashes and fly ashes from thermal power plants fired with hard coal or brown coal, waste materials from foundries containing quartz sands and waste materials from calcium carbide production, the mixture containing at least 8% hydrothermally reactive calcium oxide or equivalent amounts of other hydrothermally reactive calcium compounds and the water addition being so rated that an optimum compacting is possible and the mixture is thereafter processed by compacting to give stable firm compacts and the compacts subsequently hardened in an autoclave by saturated steam at a pressure of at least 1 bar.
