Topic: Innovative Construction Materials Shaping the Future of Hong Kong

Biography

Ir Dr Raymond Cheung has more than thirty years’ experience in civil and geotechnical engineering. He has participated in a number of mega infrastructure projects in Hong Kong under the Airport Core Programme, including Chek Lap Kok International Airport reclamation, Airport Railway and Western Harbour Crossing, before joining the Hong Kong SAR Government in the late 1990s. He is a member of various international technical committees such as the European School Scientific Committee of Landslide Risk Assessment and Mitigation (LARAM) and the International Network on Landslide Early Warning Systems (LandAware). He is currently Head of the Geotechnical Engineering Office (GEO) of the Civil Engineering and Development Department (CEDD) overseeing control of geotechnical works, setting geotechnical standards, testing and development of construction materials, mining operation and quarrying, cavern and underground space development, the Landslip Prevention and Mitigation Programme, and the landslide emergency services.

Abstract

Echoing with the Government’s policy on enhancing quality, productivity and cost-benefit of construction projects, the GEO of the CEDD has been gaining momentum in achieving these goals through researching and adopting innovative construction materials. This presentation showcases the suite of recent studies and trials on materials for different types of construction works, for examples, Blast Resistant Sprayed Concrete for tunnel projects, Ground Granulated Blast-furnace Slag (GGBS) tremie concrete for large-diameter bored piles, 3D-prined concrete elements for slope upgrading works, and the development of guidelines for deep cement mixing applications. It also highlights the Office’s upcoming materials-related initiatives, including studies on Ultra-high Performance Concrete (UHPC), light weight concrete, waste glass concrete and the use of decarbonisation technology in concrete production, in collaboration with academia and research institutes, with a view to developing new materials, promoting their uses, and setting the relevant technical standards.
