Hong is a Reader in Structures and Materials. His research lies in the area of microstructure, mass transport and durability of cementitious materials. The aim is to advance fundamental understanding of how microstructure influences performance, ageing and degradation of cement-based materials (e.g. concrete structures) using imaging, spectroscopic and modelling techniques. Key questions that drive his work are: a) How to quantify microstructure that is inherently complex, multiscale and multiphase? b) How do pores, cracks, interfaces and phase assemblage influence mass transport and deterioration processes? c) How to use microstructural information to assess current performance and predict long-term behaviour? d) How can we re-engineer the microstructure to design novel materials with improved performance, sustainability and durability?
Examples of current research include three-dimensional imaging of pore structure, understanding the influence of microcracks and interfaces, modelling mass transport processes, petrographic assessment of concrete composition and w/c ratio, developing reinforcement spacers for durable structures, low-carbon cements, self-healing concrete and clogging-resistant permeable concrete.
Hong serves in the Editorial Board of Cement and Concrete Research and as Guest Editor for the journal Materials on its special issue on Image Analysis and Processing for Cement-based Materials. He is Chair of Scientific Committee and Steering Committee member of Nanocem. He also serves as Executive Committee member of the Applied Petrography Group, as full member of the EPSRC Peer Review College and and invited reviewer for over 30 periodicals.
Hong was trained as a civil engineer at the University of Malaya, where he obtained a first class honours degree and a research MSc on calcined clay for high-performance concrete. He then joined Imperial College London to pursue a PhD on developing quantitative backscattered electron microscopy for characterising concrete microstructure. His thesis was awarded the 2006 W.C. Unwin prize. Following that, he worked as a postdoctoral Research Associate on modelling mass transport in concrete based on the techniques developed during his doctoral studies. He became an academic staff member in 2010.
Hong teaches MEng and MSc modules on Concrete Materials, Reinforced Concrete Design, Structural Mechanics and Sustainable Development. He is the Departmental Undergraduate Year 2 Coordinator and Postdoc & Fellows Champion. He also contributes to consultancy activities linked to his research thru Imperial Consultants (ICON).
