摘　　要：针对磷石膏大量堆存造成的环境风险及综合利用难题,本文基于磷石膏低成本、高附加值的利用方式的新思路,提出某磷石膏工程应用新方向—煅烧改性磷石膏空腔模盒。该空腔模盒是一种新型建筑材料,适用于现浇混凝土空心楼盖技术。研究结果表明:该产品不仅能够降低楼层荷载,与同体积钢筋混凝土材料相比,还能大幅降低建造成本,具有良好的推广应用前景。In view of the environmental risks and comprehensive utilization problems caused by large amounts of phosphogypsum,a new application direction in an phosphogypsum engineering-calcined modified phosphogypsum cavity mold box is proposed based on a low-cost and high-value-added transformation upgrading.The box is a new type of building materials,suitable for the technology of cast-in-place concrete hollow floor.The results show that this product not only can decrease floor load,compared with the same volume of reinforced concrete materials,it also can greatly reduce the construction cost with a good prospect of popularization and application.
