Iron aluminate cement clinker, preparation method thereof and iron aluminate cement
The invention relates to an iron aluminate cement clinker, a preparation method thereof and iron aluminate cement. Relates to a cement production technology. The cement clinker comprises the following minerals in percentage by mass: 30-50% of anhydrous calcium sulphoaluminate, 35-40% of dicalcium silicate and 10-30% of calcium aluminoferrite, and the total content of the three minerals is not less than 92%. The cement clinker comprises the following raw materials in percentage by mass: 10-30% of steel slag powder, 20-30% of bauxite, 40-50% of limestone, 7-10% of anhydrite and 0.1-1% of lithium carbonate. The content of MgO in the steel slag powder is not higher than 10%, and the content of MnO is not higher than 3%. The content of calcium oxide in the limestone is not lower than 50%, the content of aluminum oxide in the bauxite is not lower than 55%, the content of sulfur trioxide in the anhydrite is not lower than 45%, the content of iron oxide in the steel slag powder is not lower than 20%, and the content of calcium oxide is not lower than 35%. The production cost and carbon emission of the aluminoferrite cement are reduced, and the aluminoferrite cement has a great popularization prospect.
一种铁铝酸盐水泥熟料、其制备方法和铁铝酸盐水泥。涉及水泥生产技术。所述水泥熟料中的矿物按质量分数百分比包括:无水硫铝酸钙含量为30%~50%,硅酸二钙含量为35%~40%,铁铝酸钙含量为10%~30%,上述三种矿物总含量不低于92%。所述水泥熟料中的生料按质量分数百分比包括:钢渣粉料10~30%,铝矾土20%~30%,石灰石40%~50%,硬石膏7%~10%,碳酸锂0.1%~1%。所述钢渣粉料中MgO含量不高于10%,MnO含量不高于3%。所述石灰石中氧化钙含量不低于50%,铝矾土中氧化铝含量不低于55%,硬石膏中三氧化硫含量不低于45%,钢渣粉料中氧化铁含量不低于20%,氧化钙含量不低于35%。本发明降低了铁铝酸盐水泥的生产成本和碳排放,具有很大的推广前景。
