Brief Bio

Ir Jenny Yeung holds a Bachelor of Engineering in Civil and Structural Engineering from the Hong Kong University of Science and Technology (HKUST) and a Master of Philosophy in Geotechnical Engineering from the University of Cambridge.  She is a professional engineer in the civil, structural and geotechnical disciplines.  Over the past 30 years, she has dedicated her expertise in various aspects of the Hong Kong Slope Safety System, covering geotechnical control, landslide emergency service, landslip warning, crisis communication, public education and technical development.  Ir Yeung has been appointed by the Development Bureau as the Chairperson of the Standing Committee on Concrete Technology since 2023.  She oversees the Public Works Laboratories, delivering essential testing services to ensure construction material quality across public works projects.  She has also made substantial efforts in facilitating industry-wide dialogue and driving innovation to support Hong Kong’s transition to greener infrastructure.  Ir Yeung was an awardee of the Secretary for Civil Service’s Commendation in recognition of her long-term outstanding service to the Government and the public.  She was also awarded the Outstanding Alumni by the Department of Civil and Environmental Engineering of HKUST.  Beyond her office work, Ir Yeung’s dedication to the Hong Kong Institution of Engineers has earned her multiple prestigious honours, including the Trainee of the Year Award (1997), Young Engineer of the Year Award (2006), and the President Award (2023).

Abstract

Building on the Government’s commitment to advancing sustainable and high-performance construction, the GEO of CEDD, supported by our Public Works Central Laboratory, and the SCCT continue to champion innovations in concrete materials through collaborative research, rigorous review of testing standards and specifications, and active engagement with industry stakeholders.  This presentation will highlight our recent work on the use of Ground Granulated Blast-furnace Slag (GGBS) and other innovative materials for concrete.  The results of a systematic evaluation of GGBS concrete across diverse applications will be presented, underscoring its potential to enhance durability, lower carbon footprint, and support resilient infrastructure.  It will also cover preliminary findings on complementary solutions, including ternary blended concrete, waste-glass and lightweight concrete, and emerging decarbonisation technologies.  These studies aim to explore practical pathways towards greener construction.  Furthermore, our ongoing initiatives also reflect efforts in enhancing durability and structural safety while evaluating feasible applications in construction.  These include research into mitigating Alkali-Silica Reaction (ASR) in concrete comprising volcanic rock aggregates with the addition of supplementary cementitious materials (SCMs).  To support these innovations, the SCCT has been regularly reviewing local test standards and specification clauses, in consultation with industry stakeholders, ensuring that industry practices remain both robust and adaptable.  Collectively, these initiatives chart a forward-looking agenda to shape a more sustainable and innovative future for Hong Kong’s built environment.
