Project description

Project Name: Development and Engineering Assessment of Geopolymer Concretes for Civil Engineering Assets Use

This research focuses on developing geopolymer concrete (GPC) as a sustainable alternative to ordinary Portland cement (OPC) concrete, particularly for infrastructure applications such as road pavements. Replacing OPC with GPC enables the reuse of industrial by-products, conserves natural resources, and reduces landfill waste and associated costs.

The project evaluates the fresh, mechanical, volumetric stability, and durability properties of GPC to ensure compliance with industry standards, particularly those set by Transport for New South Wales. Key areas of investigation include optimising mix design, minimising shrinkage, and assessing the long-term performance of GPC in both laboratory and real-world conditions to facilitate its transition to field applications.

By bridging the gap between research and industry, this project aims to promote the widespread adoption of GPC in Australia’s infrastructure sector. The findings will contribute to more sustainable construction practices, reducing carbon emissions while ensuring durable, cost-effective, and environmentally responsible material solutions.

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

I was motivated by the opportunity to bridge the gap between academic research and real-world engineering applications. Seeing sustainable materials transition from the lab to practical use is crucial in addressing industry challenges. By working on an industry-led project, I can ensure my research directly contributes to the development of durable, environmentally friendly solutions for infrastructure. Collaborating with industry partners also provides valuable insights into current construction practices, regulatory requirements, and practical constraints, making my work more impactful and applicable.

What have been the highlights of your research?

The emphasis on sustainability and long-term performance has been a key highlight of my research. Developing geopolymer concrete as a low-carbon alternative to traditional cement-based materials aligns with global efforts to reduce greenhouse gas emissions in the construction sector. Investigating factors such as durability, shrinkage, and mechanical performance has reinforced the potential of geopolymer concrete for road pavements. Additionally, working on an innovative material that can withstand harsh environmental conditions while promoting circular economy principles has been particularly rewarding.

Once you have completed your PhD, what’s next?

I am eager to build a career in the construction industry, focusing on developing and implementing sustainable concrete solutions. At the same time, I would like to stay connected to academia through casual or part-time involvement in research collaborations and mentoring. This balance will allow me to apply cutting-edge knowledge in real-world projects while contributing to ongoing advancements in sustainable materials and infrastructure.

How will your research benefit Australia’s concrete ecosystem?

My research accelerates the shift toward sustainable concrete technologies, reducing carbon emissions while enhancing infrastructure durability. By optimising geopolymer concrete for road pavements, it supports resilient, low-maintenance transport networks that align with Australia’s sustainability goals. The use of industrial by-products not only reduces landfill waste and reliance on traditional cement but also promotes resource efficiency and circular economy principles. These advancements contribute to cost-effective, eco-friendly construction, reinforcing Australia’s leadership in sustainable infrastructure development.
