Release Date: 2019-05-11
At 16:00 pm on May 8th, Dr. Ye Hailong from the Department of Civil Engineering of the University of Hong Kong was invited to give a lecture entitled "Durability of Alkali-Activated Concrete: Progress and Perspective" in 4417 of Yifu Building, Jiuli Campus. Associate Professor Cui Shengai, Chen Zhao, and other teachers and students of our school attended the lecture hosted by Li Fuhai, deputy director of the Building Materials Laboratory.
Being an alumus of 2007, Dr. Ye Hailong is currently an assistant professor, doctoral tutor and national registered structural engineer of the Department of Civil Engineering in the University of Hong Kong. His main research interests include new cement-based materials, concrete materials durability, control on steel bars corrosion, etc. He has published more than 40 SCI academic papers, hosted and participated in a number of research projects funded by Hong Kong Research Grants Council (HGRGC), National Natural Science Foundation of China (NSFC), National Science Foundation ofUnited States (NSF), and National Aeronautics and Space Administration (NASA).
At the beginning of the lecture, Mr. Li Fuhai delivered a speech, introducing the guest speaker Dr. Ye Hailong and expressing a warm welcome to him. Mr. Ye first introduced the development history of alkali-activated concrete and the problems related to durability of this material. With regard to the shrinkage and cracking of alkali-excited concrete materials, Dr. Ye Hailong pointed out that alkali-activated materials possess large dry shrinkage and high cracking sensitivity, and proposed mitigation measures for shrinkage and cracking of alkali-active materials. Mr. Ye then introduced the nitrate erosion mechanism and said that it is a serious problem in coastal areas. In addition, he mentioned that alkali-activated slag has higher oxide binding capacity than conventional cement. After the lecture, Dr. Ye Hailong communicated with the students present and answered their questions with patience
