Abstract:
This burned cement clinker is a burned cement clinker including at least one selected from the group consisting of fluorine, sulfur, chlorine and bromine, and at least one metallic element(s) selected from the group consisting of elements in groups 3 through 12 of the periodic table. Preferably, the amount of fluorine is within a range from 300 to 750 mg/kg, the amount of sulfur (expressed in terms of SO3) is within a range from 1.5 to 3.0% by mass, the amount of at least one chlorine equivalent(s) selected from the group consisting of chlorine and bromine is within a range from 150 to 350 mg/kg, and the amount of at least one metallic element selected from the group consisting of elements in groups 3 through 12 of the periodic table is within a range from 0.2 to 0.8% by mass.
