廃棄されている。Currently, these steelmaking slags are placed in a simmering pot and heated for about 20 minutes.
After 12 hours, it is discharged at about 200-300'C.
As mentioned above, most of Ninal2CaO.SiO is disposed of in landfills because it expands and collapses when it undergoes the transition from β to γ, and because it contains F' and CaOXF-MgO, it has expansion and collapse properties.

After drying the slag, it is crushed and treated with an alkaline stimulant (e.g. CaOs Ca(OH)1, NaOH,
It has been found that when a small amount of Na, CO, 1, CaCL, etc. is added and water is added and kneaded, hydraulic properties are obtained.
