Summary: | The invention discloses a cement clinker produced by using waste high-silicon high-alkali limestone and a preparation method thereof. The cement clinker is prepared from the following raw materials in parts by weight: 82-87 parts of high-silicon high-alkali limestone; 5-8 parts of sandstone; 5-8 parts of tailings; 2-5 parts of fly ash; 0.2 to 1 part of desulfurized gypsum; wherein in the high-silicon high-alkali limestone, the content of CaO is 44 to 49 percent, the content of SiO2 is 8 to 12 percent, and the content of R2O is 0.7 to 1.2 percent. By optimizing ingredient selection, optimizing an ingredient scheme, selecting rate value control and adjusting the sulfur-alkali ratio by using the desulfurized gypsum, the problems of difficulty in grinding and poor burnability of the low-grade high-silicon high-alkali limestone are solved, the cement clinker is produced by using the low-grade high-silicon high-alkali limestone, the clinker strength meets the expected requirement, the enterprise benefit is greatly |
