Dicalcium silicate-calcium fluorosulphosilicate-dodecacalcium heptaaluminate cement clinker and preparation method thereof
The invention relates to the technical field of preparation of cement clinker, and particularly discloses dicalcium silicate-calcium fluorosulphosilicate-dodecacalcium heptaaluminate cement clinker and a preparation method of the dicalcium silicate-calcium fluorosulphosilicate-dodecacalcium heptaaluminate cement clinker. The cement clinker is prepared from the following mineral phases in percentage by mass: 45 to 68 percent of dicalcium silicate, 14 to 26 percent of calcium fluorosulphosilicate, 12 to 22 percent of dodecacalcium heptaaluminate, 1 to 5 percent of gehlenite, 2 to 6 percent of glass phase and the balance of unreacted raw materials and inevitable impurities. The clinker system disclosed by the invention takes the fluorine-containing sludge as a raw material, so that the resource utilization of the fluorine-containing sludge is realized, the harm of fluorine to the environment is reduced, and unstable calcium sulphosilicate is converted into stable calcium fluorosulphosilicate with low firing temperature; the overall firing temperature of the cement clinker system is obviously lower than that of traditional Portland cement, so that the energy consumption is effectively reduced, and the emission of carbon dioxide is reduced.
本发明涉及水泥熟料制备技术领域,具体公开一种硅酸二钙‑氟硫硅酸钙‑七铝酸十二钙水泥熟料及其制备方法。以质量百分比计,该水泥熟料包括如下矿物相:硅酸二钙45~68%、氟硫硅酸钙14~26%、七铝酸十二钙12~22%、钙铝黄长石1~5%、玻璃相2~6%,余量包括未反应的原料、不可避免的杂质。本发明的上述熟料体系以含氟污泥为原料,不仅实现了含氟污泥进行资源化利用,减少了氟对环境的危害,而且还将不稳定的硫硅酸钙转换成了稳定且低烧成温度的氟硫硅酸钙,使本发明的水泥熟料体系的整体烧成温度明显低于传统硅酸盐水泥,从而有效地降低了能耗,减少了二氧化碳的排放量。
