摘要：
Cement clinker, characterized in that it comprises Al 2 O 3 and Fe 2 O 3 wherein the mass ratio of Al 2 O 3 /Fe 2 O 3 is 0.05-0.62, and alkali components and C 2 S wherein the content Y (mass %) of alkali components and the content X (mass %) of C 2 S satisfy the formula: 0.0025X+0.1≦Y≦0.01X+0.8. The production of the clinker allows the incorporation of alkali components into cement with an advantageous effect of enhancement of the hydration of belite and also with suppression of the lowering of flowability, which leads to the reuse of wastes containing alkali components as a cement raw material.
