摘　　要：我国基建放缓,建筑老化,特种修复材料需求渐长。磷酸镁水泥(MPC)用于修补加固,成本与性能优化是关键。虽已知掺入工业固废可调控MPC成本与性能,且不乏MPC发展综述,但现有综述多聚焦其基础机理与应用,对固废在MPC体系中的作用机理、反应活性、物理堆积效应及化学键合原理等鲜有报道。本综述创新地从性能和机理两个维度,基于化学键合原理,系统调研固废改性MPC的研究进展,深入探讨其工作性能、力学性能等表现及作用机理,综合评述现状。最后总结现有研究,提出未来研究方向,以期改善MPC性能,降低成本,推动MPC在实际工程中的广泛应用。As China experiences a deceleration in infrastructure construction and the gradual aging of existing buildings,the impending demand for the repair and reinforcement of engineered structures is poised to surge,accompanied by a growing necessity for special repair materials.The cost-effectiveness and performance optimization of magnesium phosphate cement(MPC),a rapid repair and reinforcement material,are key considerations for its practical application.The incorporation of industrial solid waste is considered an effective means to regulate the cost and performance of MPC.Recent studies have demonstrated the potential for industrial solid waste,such as fly ash,to be utilized in the fabrication of MPC,with the objective of enhancing its performance and reducing its cost.Numerous reviews have been published on the subject of MPC development.However,the majority of these reviews have concentrated on the fundamental mechanisms and application domains of MPC,with comparatively fewer studies addressing the mechanisms,reactivity,physical stacking effects,and chemical bonding principles of solid wastes within MPC system.This review is innovative in that it investigates the research progress of solid waste-modified MPC from two perspectives:performance and mechanism,based on the principle of chemical bonding.It discusses the working,mechanical properties and mechanism of solid waste-modified MPC,and comprehensively evaluates the current situation.Finally,it summarizes existing research and puts forward future research directions with a view to improving the performance of MPC,reducing the cost,and promoting its wide application in practical engineering.
