The invention provides an unfired phosphogypsum low-carbon cementing material as well as a preparation method and application thereof. The unfired phosphogypsum low-carbon cementing material is prepared from the following raw materials in parts by weight: 35-65 parts of phosphogypsum, 20-50 parts of fly ash, 5-15 parts of carbide slag, 1-5 parts of steel slag and 1-5 parts of red mud. The unfired phosphogypsum low-carbon cementing material is mainly prepared from industrial and mining solid waste materials, and is high in cost performance; during use, the concrete has long initial setting time and high mechanical strength, is suitable for long-distance transportation, and can be applied to the fields of concrete products, road engineering and the like.
本发明提供一种免烧磷石膏低碳胶凝材料及其制备方法和应用。所述免烧磷石膏低碳胶凝材料的制备原料按重量份数包括以下组分：磷石膏35～65份、粉煤灰20～50份、电石渣5～15份、钢渣1～5份、赤泥1～5份。本发明所述免烧磷石膏低碳胶凝材料由工矿业固废材料为主制备而成，性价比高；而且在使用时初凝时间长、力学强度高，适于长距离运输，可应用于混凝土制品和道路工程等领域。
