Are you amazed by skyscrapers, stunning bridges, massive dams, or scenic roads? Or are you surprised by accidents due to potholes, collapse of old bridges, fire damage of buildings, and the urgent need to replace lead water pipes?

If your answer is yes, you may find the research on durable and sustainable construction materials as an exciting and significant field. Taking bridges as an example, there are around 208,422 steel bridges, 144,321 reinforced concrete bridges, 203,041 prestressed concrete bridges, and over 900 wooden bridges in the United States. According to the 2017 Infrastructure Report Card released by the American Society of Civil Engineers (ASCE), almost four in 10 of bridges are 50 years or older. 9.1% of the nation’s bridges were structurally deficient in 2016. The most recent federal estimate puts the backlog of rehabilitation projects for the nation's bridges at $123 billion. If we were able to extend the service life of steel, concrete, wood, and other construction materials, these bridges would have a longer service life and require less cost to repair/reconstruct.

Description of Research

Our research contributes to the goal of more durable and sustainable infrastructure. Research subjects include major construction materials such as concrete, asphalt, aggregate, steel, masonry, and wood. Recent funded research projects include:

  • Evaluation of the Effects of Deicers on Concrete Durability
  • Evaluation the Impact of Anti-Icing Solutions on Concrete Durability
  • Evaluation of Penetrating Sealers Applied to Saw Cut Faces in Concrete Pavement Joints
  • Creating Hydrophobic Concrete Joints through Innovative Additives
  • Timely and Uniform Application of Curing Materials
  • Evaluating Water-Cementitious Material Ratio (W/CM) as Acceptance Parameter for Freshly Placed Concrete

Through both laboratory experiments and field studies, we strive to solve practical, real-world problems using the latest scientific theories, methods, and technologies. We apply holistic methods to connect microscopic material mechanisms to their macroscopic engineering properties. We collaborate with internal departments such as the state-of-the-art Material Fabrication and Nano Characterization lab and external research institutes such as the pavement test track at MnROAD.

Application and Career Opportunities

Construction materials are fundamental for all civil and environmental disciplines. Therefore, the experience with our research group will prepare students for a wide range of careers such as graduate schools, materials testing firms, consulting firms, government agencies, construction companies, and materials/equipment suppliers.

Join the Research Group

We are always looking for highly motivated students. If you are interested in any topics in our research group, please contact Dr. Danny Xiao.
