%X 磷石膏作为化工厂生产磷酸时的副产物，主要成分为二水硫酸钙，整体呈酸性，含有磷酸、氟等有害物质，且放射性超标，露天堆存会对环境造成污染。将磷石膏与多种物料进行复合可以制备新型材料，其在性能、实用性等方面都不逊色于原材料，此举可以有效提高磷石膏的利用量，缓解因磷石膏堆存所引起的较为严重的环境问题，为环境治理提供了新途径。本文通过结合国内外相关学者对磷石膏、陶粒在建筑领域与桥梁工程的研究利用现状，探讨磷石膏与陶粒对混凝土性能的影响因素，并综合评价磷石膏、陶粒在新型混凝土中所发挥的作用。<br />
Phosphogypsum as a by-product of phosphoric acid production in chemical plants, the main component is calcium sulfate dihydrate, which is acid and contains phosphoric acid, fluorine and other harmful substances; and when the radioactivity exceeds the standard, open storage will cause environmental pollution. By combining phosphogypsum with a variety of materials, new materials can be prepared, which is not inferior to raw materials in terms of performance and practicability, and can effectively improve the utilization of phosphogypsum, alleviate the more serious environmental problems caused by the accumulation of phosphogypsum, and provide a new way for environmental governance. Based on the research and utilization status of phosphogypsum and ceramsite in the field of construction and bridge engineering by relevant scholars at home and abroad, this paper discusses the influencing factors of phosphogypsum and ceramsite on the performance of concrete, and comprehensively evaluates the role played by phosphogypsum and ceramsite in new concrete.
