摘要：利用生石灰对磷石膏进行改性，得到改性磷石膏，将改性磷石膏、矿渣粉、水泥按一定比例混合均匀，通过粉磨制得改性磷石膏矿渣水泥，分析研究了改性磷石膏矿渣水泥的性能及改性磷石膏矿渣水泥在混凝土和路基材料中应用的可行性。结果表明：与未改性磷石膏相比，利用改性磷石膏制得的水泥早期强度有所提高；以改性磷石膏矿渣水泥为胶凝材料的混凝土和路基材料的早期强度增长较慢，但中后期强度可实现稳定增长；将改性磷石膏应用于混凝土和路基材料中时，其中的磷、氟等杂质可得到有效固化，对生态环境的影响较小。研制的改性磷石膏相关产品具有良好的结构功能性与安全环保性，已成功应用于道路工程。 Abstract: The phosphogypsum was modified with quicklime to obtain modified phosphogypsum. The modified phosphogypsum, slag powder and cement were mixed uniformly in a certain proportion, and then ground to obtain modified phosphogypsum slag cement. The properties of modified phosphogypsum slag cement and the feasibility of modified phosphogypsum slag cement in concrete and roadbed materials were analyzed. The results show that compared with unmodified phosphogypsum, the early strength of cement prepared with modified phosphogypsum is improved. The early strength growth of concrete and roadbed materials using modified phosphogypsum slag cement as cementitious material is slow, but the strength can achieve stable growth in the middle and late stages. When the modified phosphogypsum is applied to concrete and roadbed materials, impurities such as phosphorus and fluorine can be effectively cured, and the impact on the ecological environment is small. The developed modified phosphogypsum related products have good structural functionality and safety and environmental protection, and have been successfully applied to road engineering.
