The invention discloses a cement kiln co-processing polluted soil admixture as well as a preparation method and an application thereof. The cement kiln co-processing polluted soil admixture is prepared from the following substances in parts by weight: 65-85 parts of cement kiln co-processing polluted soil, 2-5 parts of desulfurized gypsum, 5-25 parts of fly ash, 5-15 parts of blast furnace slag, 1-10 parts of magnesium slag, 1-6 parts of hydrated calcium chloroaluminate, 0.1-0.5 parts of ferrous sulfate and 0.5-5 parts of regulating additive. The invention provides a safe and efficient subsequent utilization path for co-processing the polluted soil by the cement kiln. Moreover, the admixture disclosed by the invention has higher hydration activity, the strength of admixture-doped cement can be improved, a high-quality admixture is expanded for cement manufacturing, and energy conservation and emission reduction of cement production are promoted.
水泥窑协同处置污染土壤混合材及其制备方法和应用，按重量份由以下物质组成：水泥窑协同处置污染土65‑85份、脱硫石膏2‑5份、粉煤灰5‑25份、高炉矿渣5‑15份、镁渣1‑10份、水化氯铝酸钙1‑6份、硫酸亚铁0.1‑0.5份，调节助剂0.5‑5份。本发明为水泥窑协同处置污染土提供了一个安全高效的后续利用的路径。而且，本发明的混合材具有较高水化活性，能够增加掺混合材水泥的强度，为水泥制造拓展了优质混合材，促进水泥生产的节能减排。
