Civil and Environmental Engineering
Ali Amani is a Research Associate and concrete materials specialist in the School of Civil and Environmental Engineering at UNSW Sydney. His work integrates concrete technology, pavement engineering, sustainable construction materials, durability assessment, and applied materials research.
At UNSW, Ali collaborates with Transport for NSW to develop and evaluate concrete materials for rigid pavement applications. His work includes concrete mix design, laboratory testing, material characterisation, performance assessment, data analysis, and compliance with relevant Australian Standards and Transport for NSW specifications.
Ali has experience in low-carbon binder systems, supplementary cementitious materials, recycled and alternative materials, concrete durability, transport properties, life-cycle assessment, and embodied-carbon evaluation. Before joining UNSW, Ali gained several years of industry professional experience in civil engineering, concrete construction, materials quality control, project coordination, and infrastructure delivery.

Ali’s research focuses on developing low-carbon concrete and other environmentally friendly infrastructure composites, and he is keen to understand their environmental impacts. His work aims to reduce the environmental impact of concrete while maintaining the mechanical performance, durability, constructability, and service-life requirements needed for transport and civil infrastructure. He investigates how the physical and chemical characteristics of these materials influence cement hydration, pore structure, strength development, dimensional stability, transport properties, and long-term durability. Ali is actively involved in developing environmentally friendly low-carbon concrete alternatives and focuses on the potential contribution of concrete carbonation to carbon dioxide sequestration over the material’s service life and beyond.
Ali is currently involved in industry-supported research with Transport for NSW concerning concrete pavement materials and mix designs aligned with the requirements of the TfNSW R83 specification. This work includes benchmarking conventional and lower-carbon concrete mixtures, evaluating biochar-integrated concrete, and translating experimental findings into technically robust and practically applicable recommendations for pavement engineering. Ali’s broader research interests include:
- Low-carbon and high-performance concrete
- Carbonation and carbon dioxide uptake in concrete
- Cement chemistry, hydration, and concrete microstructure
- Supplementary cementitious materials and alternative binders
- Concrete pavement materials and rigid pavement performance
- Sustainability and service-life assessment
- Life-cycle assessment, embodied carbon, and environmental product declarations
