Brief description of lab
Investigate and understand controlling mechanisms of corrosion in exposed structural steelwork under local environments in Hong Kong, as well as investigation and development of corrosion monitoring methods, corrosion engineering technology, prediction, assessment and protection methods to both reinforced concrete structures and steel-concrete composite structures.

Research themes
- To investigate the atmospheric corrosivity in local areas in Hong Kong, and to study the atmospheric corrosion chemicals, corrosion mechanisms, and corrosion rates of exposed steelwork under local environments.
- To investigate various corrosion monitoring methods in buildings and civil engineering structures using internet-based monitoring systems and corrosion sensors.
- To investigate the conventional galvanisation method with Zinc, and the innovative modern galvanisation process with Zinc and Aluminium alloys as well as the control of coating thicknesses, and surface quality, and the prolonged use of various fluxing solutions.
- To investigate corrosion protection and repair technology including rusts and hydrated iron oxides, rust removal, chemical treatments, service life of rusted steelwork, and service life after repair.
Projects
- Atmospheric corrosivity was measured through mass loss tests on exposed steel plates in 7 different sites throughout Hong Kong since 2010.
- Improved galvanisation processes for enhanced ductility and durability.
- Corrosion monitoring in residential houses using internet-based monitoring systems and corrosion sensors – InnoCell Building at HKSTP in Shatin, Nam Cheong Transitional Housing in Sham Shui Po.
- Corrosion monitoring of steel flexible barriers against rockfall in rural areas.
- Control of local environments to prevent occurrence of corrosion.
