Prof. Xiangping Xian, Assistant Professor of the Department of Architecture and Civil Engineering of City University of Hong Kong, visited IAPME on December 26, 2024. During his visit, he delivered an insightful presentation titled “The improvement of corrosion resistance of wet-cast concrete subjected to early-age ambient pressure carbonation curing”. The seminar was hosted by Prof. Binmeng Chen, who extended the invitation to Prof. Xian.
Prof. Xian obtained his master‘s degree in 2017 and Ph.D. in Civil Engineering in 2021 from McGill University. In 2023, he was awarded a Marie Sklodowska-Curie Future Roads Fellowship, supervised by Professor Abir Al-Tabbaa of Cambridge University. His research focuses on developing eco-friendly and functional cement-based products using OPC, industrial waste, municipal solid waste incineration, etc., through Carbon Capture, Utilization, and Storage (CCUS) techniques, contributing to environmental protection and sustainable development. Additionally, Prof. Xian also has interests in automated construction, 3D printing of green building materials, the engineering applications of durable materials and so on.
During lecture, Prof. Xian emphasized the potential of developing early-age ambient pressure carbonation curing as a means to mitigate corrosion risk and enhance resistance. This approach involves preventing deep CO2 penetration and chemically and physically densifying concrete surface layer. He then presented two methods for evaluating the effectiveness of ambient pressure carbonation on the corrosion resistance of concrete. These methods not only underscore the efficacy of his work but also highlight its potential contributions to sustainability and the promotion of a circular carbon economy.
Prof. Xian also engaged in a lively discussion with several students on topics such as accelerating the carbonation of concrete. The seminar provided attendees with a comprehensive understanding on corrosion resistance of wet-cast concrete.
