On the afternoon of October 25th, the School of Urban Railway Transportation invited Professor Li Longyuan from the School of Engineering, Computing and Mathematics at the University of Plymouth, UK, to deliver an academic lecture titled Chloride Diffusion in Concrete - Mechanism, Experiment, and Simulation for the faculty and students. The lecture was conducted in the form of an online conference and was hosted by Professor Li Zaiwei from SURT.
At the meeting, Professor Li Longyuan delivered a lecture on the topic of chloride diffusion in concrete. Chloride-induced reinforcing steel corrosion is one of the major durability issues for designing reinforced concrete (RC) structures. According to the statistics analysis on RC structures used in developed countries, almost one-third of the costs are spent on the repair of RC structures which is related to the corrosion of reinforcing steel.In this lecture, Professor Li gave an overview on the chloride diffusion in concrete. He covered the mechanisms of chloride penetration in concrete, the theoretical models used to describe chloride penetration, the experimental methods currently used to determine chloride diffusion coefficient in concrete, the numerical models used to predict the chloride penetration in concrete, as well as how the individual constituents mixed in the concrete affect the diffusivity of concrete and what methods can be used to protect the reinforcing steel from the chloride-induced corrosion.
After the lecture, faculty and students actively engaged in discussions with Professor Li Longyuan on relevant academic issues. The atmosphere at the meeting was enthusiastic, and everyone present listened attentively to the lecture, further broadening their academic perspectives.
Professor Li Longyuan is Professor of Structural Engineering in School of Engineering, Computing and Mathematics at University of Plymouth, UK.
