The invention discloses a cement raw material and a cement preparation method, which relate to the technical field of building materials. The cement raw material comprises the following components by weight: 80-95% of a calcareous material, 3-10% of a siliceous material, 1-5% of an iron material, and 1-5% of ferrous sulfate. According to the cement raw material disclosed by the invention, the ferrous sulfate is adopted to replace part of ferrous materials in the original cement raw material, so that the production cost is reduced, the chromium content in the cement can be reduced due to low chromium content in the ferrous sulfate, and the influence on the environment and human bodies due to overhigh chromium content is avoided.
本发明公开了一种水泥生料及水泥的制备方法，涉及建筑材料技术领域，该水泥生料，包括以下重量百分比的组分：钙质材料80％‑95％、硅质材料3％‑10％、铁质材料1％‑5％和硫酸亚铁1‑5％。本发明的水泥生料采用硫酸亚铁替代原有的水泥生料中的部分铁质材料，不仅降低生产成本，而且由于硫酸亚铁中铬含量低，可以降低水泥中铬含量，避免因铬含量过高而对环境和人体产生影响。
