About Kejin

Dr. Wang has a split appointment with the Department of Civil, Construction, and Environmental Engineering at Iowa State University. She does research on the material properties of portland cement concrete and concrete durability. 


  • PhD, Civil Engineering, University of California, Berkeley, 1994 
  • MS, Civil Engineering, Chinese Academy of Sciences (Beijing, China), 1985 
  • BS, Civil Engineering, Hefei University of Technology (Hefei, China), 1982 

Interest Areas

  • Chemistry and microstructure of concrete (cement hydration and air void structure) 
  • Nano-technology and application in concrete (nano-silica, nano-clay and nano-limestone) 
  • Workability and rheology of concrete
  • Durability of concrete (freezing-thawing, alkali-silica reaction, and corrosion of reinforcement)
  • Sustainable concrete materials (uses of slag, fly ash, silica fume, recycled aggregate, geopolymer, etc.)
  • Advanced concrete technology (self-consolidating concrete, roller compacting concrete, mass concrete and pervious concretes)
  • Concrete pavement (mix design, quality control, distress analysis, and repair)
