The sustainable material and structure lab's primary professional and scholarly contributions have dealt with material design, characterization, test and analysis for sustainable civil infrastructure applications, especially on self-healing, self-regulation, damage mechanism diagnosis and multi-physical interactions in asphalt mixtures, concrete or geopolymer. The sustainable material-related research incorporated municipal solid waste such as scrap tire rubber or glass into concrete for improved durability and bio-processed waste Kraft lignin as adhesives or coating materials. The structure resilience-related research has been conducted on smart actuator design, test and simulation for structural vibration reduction and power distribution structure resilience simulation under multi hazard loading conditions.
The research has been involved with other multidisciplinary areas: multiphysics, computational simulation, molecular dynamic simulation, image-based computation, advanced material characterization methods, nondestructive testing, damage detection and mechanism, smart polymer chemistry, alternative and sustainable infrastructure materials, active-material based actuator design, aerodynamic and aeroelastic simulation, and structural resilience for cross-laminate timber building, energy storage and power distribution system.
Developed the advanced characterization methods and simulation model for damage in concrete and asphalt mixtures. Develop new sustainable materials with recycled components.
This research developed durable concrete and benefit the industries involved with concrete design and construction in cold regions. The durability of concrete plays a central role in the sustainability of the whole infrastructure system on which such regions depend for their development. In this project, research and educational activities will be integrated to promote teaching, training, and learning for the K-12 students and teachers, undergraduate and graduate students in engineering and science, and professional engineers. Additionally, the methodology developed in this project for understanding the frost damage mechanisms of concrete will be applicable for solving other durability issues such as salt scaling and chemical reaction.
