Synopsis

The presentation encompasses four parts – (1). General model for reinforcement corrosion: Including Tutti’s general model for reinforcement corrosion comprising initiation period, propagation period, and severe damage period.  (2). Chloride models and application: Including history of chloride model development and recent progress; application of chloride models in tunnel and underground environment.  (3). Carbonation models and application: Including history of carbonation models and recent progress; application of carbonation models in tunnel and underground environment.  (4). Corrosion modelling: Including prediction of reinforcement corrosion in tunnel and underground environment.

About the Speaker

Dr Shengjun Zhou is a Director and National Engineering Manager in Bell Asset Engineering Pty Ltd in Australia.  He received PhD degree in University of Dundee (UK) and Master of Engineering in Tsinghua University (China).  He previously held principal positions in AECOM, Ancon Beton, and BCRC in Australia.  Prior to that, he had been R&D Manager in Boral and Research Fellows in Dundee and Singapore.  Altogether, he has 39-year postgraduate experience in concrete research and engineering, with special focus on concrete durability design/assessment and early age thermal analysis for cracking control.

He has made ground-breaking progress in establishing (‘third-generation’) analytical models suitable to predict chloride diffusion process in concrete with an increasing chloride surface concentration, which commonly occurs in concrete exposed in a chloride laden environment during initial exposure period.  In addition, he has also developed relevant methods to combine the chloride profiles in the consequent periods having totally different diffusion conditions (or input parameters).  He has established relationship between key input parameters in (‘second-generation’) empirical chloride model and analytical chloride model to resolve the long-standing confusion and dispute in this topic.  He has also established (‘third-generation’) numerical model to predict carbonation in concrete commonly exposed to gradually changing climate conditions (e.g. increasing CO2 due to carbon emission, increasing temperature due to global warming, and decreasing humidity).  These models & methods enable accurate and reliable service life prediction of reinforced concrete, never achieved before.  They have wide application and been used successfully in various major projects.
