Method for preparing cement clinker under oxygen-rich combustion condition and cement material

Abstract

The present application belongs to the technical field of a cement material, and specifically relates to a method for preparing cement clinker and a cement material. The method for preparing cement clinker provided by the present application comprises the following steps: 1) preparing cement raw meal; 2) calcining the cement raw meal under an oxygen-rich atmosphere, the oxygen-rich atmosphere being mixed gas of oxygen and carbon dioxide in a volume ratio of (0.21-0.61): (0.39-0.79). The method for preparing the cement clinker of the present application is not easy to generate the pollutant NOx, the main component in the flue gas is CO2, which is more conducive to carbon capture and sequestration, and the cement clinker obtained has a high content of C3S, and the cement clinker has good performance (hydration effect and stability).
