Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a solidifying material for enhancing hot strength for ore powder which ensures the cold strength of a pellet which is equal to or higher than that obtained by the conventional solidifying material, and is also excellent in development of the hot strength and wear resistance of the pellet, to provide a pellet using the same, and to provide a method for producing the same. SOLUTION: Disclosed are: the solidifying material for enhancing hot strength for ore powder, which contains portland cement and a pozzolana reactive substance and does not contain slag, wherein the specific surface area of the pozzolana reactive substance is ≥2,500 cm2/g, and the pozzolana reactive substance is fly ash; the solidifying material for enhancing hot strength for ore powder, wherein the cement is high early strength portland cement; and the solidifying material for enhancing hot strength for ore powder, wherein alkanolamine is contained. Also disclosed are the pellet using the solidifying material for enhancing hot strength for ore powder and a method for producing the same. COPYRIGHT: (C)2010,JPO&INPIT |
