More Information
Summary:Cement clinker, characterized in that it comprises Al2O3 and Fe2O3 wherein the mass ratio of Al2O3/Fe2O3 is 0.05-0.62, and alkali components and C2S wherein the content Y (mass %) of alkali components and the content X (mass %) of C2S 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.
