Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a quality determination method of coal ash slurry allowing previous evaluation of fluidity of concrete after the coal ash slurry is added in a manufacturing stage of the coal ash slurry before the stage of adding the coal ash slurry to the concrete. SOLUTION: In the quality determination method of the coal ash slurry, the quality of the coal ash slurry slurried by mixing and stirring coal ash and water is determined. Zeta potential of the coal ash slurry is measured, and the quality of the coal ash slurry is determined based on the zeta potential. COPYRIGHT: (C)2008,JPO&INPIT
