Low-alkali cement clinker, low-alkali cement and preparation method of low-alkali cement
The invention provides low-alkali cement clinker, low-alkali cement and a preparation method of the low-alkali cement, and belongs to the technical field of cement. The low-alkali cement clinker is prepared from the following raw materials in parts by weight: 55-65 parts of low-alkali limestone, 15-30 parts of carbide slag, 0-5 parts of coal-fired slag, 3-10 parts of fly ash, 0-8 parts of copper slag and 1-5 parts of fluorite tailings. According to the low-alkali cement clinker provided by the invention, the alkali content in the cement clinker is reduced, the conditions for producing low-alkali cement are met, and the cement production cost is reduced.
本发明提供了一种低碱水泥熟料、低碱水泥及其制备方法，属于水泥技术领域。一种低碱水泥熟料，由如下重量份的原料制成：低碱石灰石55‑65份、电石渣15‑30份、燃煤炉渣0‑5份、粉煤灰3‑10份、铜矿渣0‑8份、萤石尾矿1‑5份。本发明提供的低碱水泥熟料，以降低水泥熟料中的碱含量，满足生产低碱水泥的条件，降低水泥生产成本。
