うになりつつある。2. Description of the Related Art Municipal waste and industrial waste are often incinerated. The incineration residue whose volume has been reduced by incineration has been landfilled. However, as it becomes increasingly difficult to secure landfill sites, incineration residues are melted in a melting furnace, then solidified, and reused as roadbed materials, aggregates, blocks, and the like.

いる。In general, it is known that slag discharged from a melting furnace in a high-temperature molten state becomes a vitreous slag when rapidly cooled, and becomes a crystallized slag having a crystal structure when gradually cooled. Slag treatment in relatively large-scale melting furnaces
Due to the simplicity of the treatment, a water granulation treatment of quenching has been the mainstream, but the slag produced is non-crystalline and thus brittle and difficult to reuse. Therefore, in recent years, there has been an increasing movement to use slag as a crystallized slag having a high strength by air cooling or slow cooling and effectively utilizing the slag as a roadbed material, a concrete aggregate, and the like, which are in great demand.

いた。However, crystallized slag actually has a considerable variation in specific gravity, strength and the like. Even if the particle size is adjusted only after crushing, other slags such as specific gravity and strength can be satisfied even if the particle size standard can be satisfied. It is difficult to satisfy the standard and, for example, when used as a roadbed material, most of them can only be used as a lower layer roadbed material, and have low added value.
