I have been engaged in research on the resource utilization of construction waste, the preparation and performance control methods of alkali-activated high-performance concrete, machine learning-assisted design of alkali-activated materials, and micro-scale numerical simulation for a long time. I have innovated the preparation method of high-strength alkali-activated geopolymers from waste brick powder, proposed a complete set of key technologies for shrinkage control and crack prevention of alkali-activated ultra-high performance concrete, established multiple performance prediction models and feedback optimization models for alkali-activated materials, and achieved precise and intelligent design of alkali-activated materials. My research interests include resource utilization of construction demolition waste, alkali-activated ultra-high performance concrete, alkali-activated foamed materials, artificial intelligence-assisted material design, repair and reinforcement materials and meso-scale numerical simulation.
