Wengui's research interests are in the field of connecting materials property of concrete to structural response, specifically including:
(1) Intelligent/functional concrete (self-sensing, self-healing, self-powering, hydrophobicity, photocatalysis, energy-saving)
(2) Recycled aggregate concrete materials and structures
(3) Solid waste recovery for sustainable construction materials
(4) Carbon-neutral concrete and CO2 mineralized concrete
(5) Concrete nanotechnology (nanomodification, nanocharacterization)
(6) Concrete durability (chloride transport, reinforcing corrosion)
(7) Seawater sea sand concrete materials and structures
(8) Fire resistance of concrete
(9) Pavement materials and technology
Wengui’s research is focused on advancing intelligent/smart concrete, which has integrated self-healing and self-sensing capacities, to develop sustainable and intelligent infrastructure that is more serviceable and easier to maintain. When concrete is subjected to stress from carrying-on and environmental factors, microscopic defects can form, allowing water, salts, and chemicals to penetrate the concrete. These defects can develop into cracks, which are the major cause of concrete deterioration, including early age cracking due to restrained shrinkage and chloride-induced corrosion of reinforcing steel. To overcome this issue, Wengui has used a permeability-reducing admixture to create self-healing concrete. This type of concrete has an intrinsic ability to rapidly heal restrain shrinkage-induced cracks, thereby preventing early chloride-induced corrosion and significantly reducing maintenance costs.Â
Meanwhile, Wengui has developed a cement-based sensor that has integrated self-sensing and hydrophobic abilities, making it more robust and resilient for use in future infrastructure. Compared to conventional sensors, this new sensor can provide more accurate diagnosis and prognosis of the presence, location, and severity of cracks in concrete assets. Through his research, Wengui aims to improve the serviceability and resilience of concrete, as well as its overall performance and safety. By making concrete assets more efficient to operate and maintain, he anticipates major reductions in asset management costs.Â

Driven by a passion to generate a positive impact from his research, Wengui has collaborated industry partners to develop the latest guidance for assessing the impact of climate change on infrastructure in Queensland. He also has effectively improved the durability of concrete under harsh mining environments in Western Australia, creating 10 new jobs, and improving the safety and maintenance of operational mine sites. Working with BMT Commercial, Wengui developed a methodology and guidance for asset managers to assess the impact of climate change on the service life of infrastructure. His currently work on hydrophobic concrete is aimed at extending the service life of concrete infrastructure, estimating to save $7.8 billion in annual maintenance costs in Australia.Â
Additionally, he actively engages with the community through lectures and workshops to promote the use of smart concrete and sustainable construction materials, inspiring the next generation of researchers and engineers to pursue their dreams and make a positive impact on society.
