Biography

I am currently a research student at the University of Sydney funded by SmartCrete Fit for Purpose Concrete Project under the supervision of Professor Marjorie Valix and Professor Liyong Tong. I finished my Bachelor of Aeronautical Engineer Honours in June 2023 at the University of Sydney. I started research here in July 2023. My research area includes geopolymer concrete and modelling of assets.

Project description

Fit for Purpose Concrete – Geopolymer. This research aims to replace currently used ordinary portland cement for civil and infrastructure purposes with a more recently developed geopolymer concrete. The research will be mainly testing works in laboratory along with field testing to validate. Meanwhile, service life modelling will predict and simulate the real service life of the infrastructure, for this research, access chamber within sewer system. The ultimate purpose is to develop specific protocols and standards of using geopolymer in real life with all supplementary results and validations so industry can benefit from using geopolymer as geopolymers have been proven to perform better and are more eco-friendly to the world.

What led you to undertake an industry-led research project?

Professor Marjorie Valix

What have been the highlights of your PhD?

Great to undertake experiments.

Where do you see your future – industry or research? 

Either one is fine, really depends on the opportunity at that time.

How will your research benefit Australia’s concrete ecosystem?

Geopolymer is proven to be a better substitute of ordinary portland cement or other kinds of concrete in the industry. It costs less and also carbon emission is low.
