Substance formed during processing of liquid steel or during production of iron castings. Consists primarily of fused silicates and trace elements as oxides as well as trace of alloying elements.
Leaching data of different kinds of slags im mg/l using leaching
method DIN 38414-S4 in comparison with limit values of the German
Federal Drinking Water Regulation
6.5 – 9.5
ABS: air-cooled blast furnace slag
GBS: granulated blast furnace slag
TOV: Trinkwasserverordnung (German Federal Drinking Water
Slag leachates fulfil the
criteria of the German Federal Drinking Water Regulation. Compared with
stamdard sea water or mineral water, the requirements for slag leachates
are very strict, and application of slags in protected areas (protected
area for drinking water supply) is not possible.
With the exception of
sulfate of ABS, which is slightly soluble in water, slags are insoluble
in water. Heavy metals occur only in traces, and their concentrations
are below limits set by the German Federal Drinking Water Regulation.
With the exception of sulfate in ABS, slags are insoluble. Slag
leachates fulfil the quality criteria of the German Federal Drinking
Water Regulation, and they pose no risk to human health (FEhS 2000
