Prof. Jun Chang has worked in building Materials institute of Dalian University of Technology from 2011. His research field mainly focus on special cement for resistance seawater corrosion. received Ph.D. in Materials science at Wuhan University of Technology He rec ogy 2004 and worked as a Visiting professor in McGill University, Montreal, Quebec, Canada on 2005-2006.
His research work mainly focus on special cement materials, which is calcium barium (strontium) sulphoaluminate (CBaSA and CSrSA) cement and it has excellent performance, such as rapid hardening, early strength and high strength, impermeability and seawater corrosion resistance. Calcium barium (strontium) sulphoaluminate cements, plugging materials and concrete interface agent were invented based on CBaSA, CSrSA and C2S minerals.
The award of National prize for technological inventions was obtained based on this research work. The series materials were widely used to repair and strengthening in coastal concrete engineering.
