My research focuses on developing innovative pathways for repurposing industrial solid wastes into value-added green construction materials. One primary area investigates the high-dosage utilization of phosphogypsum by constructing a synergistic "carbonation pretreatment-alkali activation" system to activate its latent cementitious properties and enhance stability, ultimately creating high-performance binders when combined with other solid wastes like slag. Another key direction explores CO₂ mineralization techniques using alkaline wastes such as recycled concrete powder and steel slag, where I develop carbonation-performance coupling models to simultaneously enhance CO₂ sequestration efficiency and mechanical properties. This work involves designing experimental setups that simulate industrial flue gas conditions, systematically studying reaction mechanisms and microstructural evolution to advance the engineering application and scalable adoption of sustainable building materials.
