Solid waste-based magnesium phosphate cements: Preparation, performance and solidification/stabilization mechanism

Abstract Magnesium phosphate cement (MPC) is a promising material for solid waste recycling. Other than undoped MPC studies, this review systematically summarizes 121 relevant literatures on the solid waste-based MPC published in the past 15 years. More than 40 types of solid waste-based MPCs are integrally evaluated. Besides, the hydration kinetics of MPC and action principle of doped elements are emphatically explored and discussed. Moreover, the gaps of solid waste-based MPC are analyzed from cost, performance, and safety. Finally, the future development trends of solid waste-based MPC, including life cycle assessment, long-term stability and priority of mechanism studies are investigated.
