Zusammenfassung:	To provide a manufacturing method of an unburned carbon-reduced fly ash, capable of easily manufacturing a high quality fly ash with reduced unburned carbon at low cost without modifying fly ash itself.SOLUTION: A manufacturing method of an unburned carbon-reduced fly ash includes: a step of applying impact or vibration to a container where a fly ash raw material is kept in an approximately vertical direction to float the unburned carbon to a surface of the fly ash raw material; and a step of blowing or sucking the unburned carbon floated on the surface of the fly ash raw material to remove the unburned carbon from the fly ash raw material.SELECTED DRAWING: Figure 3 【課題】フライアッシュ自体を改質することなく、未燃炭素を低減した高品質のフライアッシュを容易かつ低コストで製造することができる未燃炭素低減フライアッシュの製造方法を提供する。【解決手段】未燃炭素低減フライアッシュの製造方法は、フライアッシュ原料が入れられた容器に対して、略上下方向に衝撃または振動を与え、フライアッシュ原料の表面に未燃炭素を浮上させる工程と、フライアッシュ原料の表面に浮上した未燃炭素を吹き飛ばしまたは吸引し、フライアッシュ原料から未燃炭素を除去する工程と、を備える。【選択図】図３
