磷石膏填充墙研究现状与应用进展

Research status and application progress of phosphogypsum infilled walls

目前全国废弃磷石膏的累积量达到了3亿t,其随意堆放造成了土地资源浪费与环境破坏,将磷石膏运用于填充墙体系不仅可以达到固废利用,而且节约能源,有利于经济发展。在2020年"两会"期间,全国人大代表提出在全国全面实施"以渣定产",为了加快中国磷化工生态绿色、高质量发展进程,基于国内外磷石膏的研究发展现状,总结了磷石膏的优缺点,探究了磷石膏填充墙的发展潜力;结合磷石膏填充墙实际应用现状,发现磷石膏应用于填充墙结构体系中的不足,最后对磷石膏填充墙研究及应用方向提出展望,为装配式磷石膏填充墙提供参考,助力磷化工行业可持续发展。

At present,the accumulated amount of waste phosphogypsum in China has reached 3×108 tons,which causes waste of land resources and environmental damage.Using phosphogypsum in infilled wall system can not only achieve solid waste utilization,but also save energy,which is advantageous to economic development.During the"two sessions"in 2020,deputies to the National People′s Congress proposed to comprehensively implement the"production based slag"policy.In order to speed up the ecological green and high-quality development process of phosphorus chemical industry in China,based on the research and development status of phosphogypsum at home and abroad,the advantages and disadvantages of phosphogypsum were summarized and the development potential of phosphogypsum infilled walls were explored.Combined with the actual application status of phosphogypsum infilled walls,the shortcomings of phosphogypsum used in infilled walls structure system were found.Finally,the research and application direction of phosphogypsum infilled walls were prospected,which could provide reference for assembly type phosphogypsum infilled walls and help the sustainable development of phosphorus chemical industry.
