Phosphogypsum-based cement
The invention relates to the field of cement, in particular to ardealite-based cement. The phosphogypsum-based cement comprises the following raw materials in percentage by weight: 2-5% of Portland cement clinker, 21-51% of slag, 35-65% of phosphogypsum and 10% of limestone. The phosphogypsum cement has good workability, strong plasticity and good weatherability, the amount of phosphogypsum in the phosphogypsum cement is large, a large amount of phosphogypsum produced by phosphorus chemical enterprises can be consumed, resources are saved, and the production cost of the cement is reduced.
本发明涉及水泥领域，具体而言，涉及一种磷石膏基水泥。该磷石膏基水泥按重量百分比计包括以下原料：硅酸盐水泥熟料2‑5％、矿渣21‑51％、磷石膏35‑65％和石灰石10％。该磷石膏水泥具有良好的和易性、可塑性强、耐候性好，且该磷石膏水泥中的磷石膏用量大，可大量的消耗磷化工企业产生的磷石膏，节约资源，并降低了水泥的生产成本。
