摘要: 工业固废磷石膏的大量堆存与环境污染已成为严峻挑战,而传统水泥产业的高能耗与高排放特性也背离我国“双碳”战略目标。开发磷石膏基固废碱激发胶凝材料以部分替代水泥,是同步解决上述问题的有效途径。本文基于磷石膏的理化特性,系统阐释了磷石膏基固废碱激发胶凝材料的胶结硬化机理;梳理并对比了典型磷石膏基固废碱激发胶凝材料体系的性能特点;综述了该类材料在道路基层、填充工程等领域的应用现状与发展潜力。本研究旨在为磷石膏在高性能、高附加值和环境友好型工程材料中的资源化利用提供理论支撑与技术参考。

Abstract: The massive stockpiling of industrial solid waste phosphogypsum, and its associated environmental pollution have become severe challenges. Simultaneously, the high energy consumption and emissions of the traditional cement production increasingly conflicts with China's "Dual Carbon" strategic goals. Developing phosphogypsum-based solid waste alkali-activated cementitious materials to partially replace cement offers an effective pathway to simultaneously address these issues. In this paper, based on the physicochemical characteristics of phosphogypsum, systematically elucidates the cementation hardening mechanisms of phosphogypsum-based solid waste alkali-activated cementitious materials; reviews and compares the characteristics of representative phosphogypsum-based solid waste alkali-activated cementitious systems; and summarizes the current application status and future potential of these materials in engineering fields such as road base layers and fill applications. The research aims to provide theoretical support and technical references for producing high-performance, high-value-added, and environmentally friendly engineering materials from phosphogypsum.

Key words: phosphogypsum, alkali-activation, solid waste cementitious material, cementation hardening mechanism, engineering application
