Wedoany.com Report on Mar 18th, Boral Limited in Australia announced on February 16, 2026, in Sydney that it has completed the development of Australia's first low-carbon concrete product using locally sourced calcined clay. This marks a new advancement in the field of sustainable building materials. This calcined clay concrete is designed to reduce carbon emissions from cement and concrete production while supporting the development of Australia's infrastructure and construction industry.
The development of this calcined clay concrete is based on extensive laboratory research and large-scale field trials, which have demonstrated the technical feasibility of using calcined clay as a supplementary cementitious material. The project began in 2024 and involved collaboration with the University of Technology Sydney, Transport for New South Wales, and Calix. It received support from SmartCrete CRC, with funding from industry partners and grants from the Australian federal government. Preliminary research was jointly conducted by Boral and the University of Technology Sydney between 2020 and 2024.
The new calcined clay concrete formulations include binary and ternary blends, which were tested under real-world conditions at Boral's cement operations site in Maldon, New South Wales. Trial results showed that the concrete exhibited good workability during pouring, with performance comparable to traditional low-carbon concrete, making it suitable for large-scale production and infrastructure applications. The development phase also included customer trials in collaboration with the North East Link project in Victoria and the University of Melbourne, where recycled clay was used to construct test slabs, showcasing the potential for circular construction practices.
Vik Bansal, CEO and Managing Director of Boral Limited, stated, "Boral is committed to leading the transition to a low-carbon future. Our calcined clay concrete is a significant step forward in our innovation journey and our goal of achieving net-zero emissions. This work ensures that we can continue to provide sustainable solutions for Australia's construction and infrastructure needs while meeting our customers' expectations." Dr. Ali Nezhad, Head of Sustainability and Innovation at Boral, added, "From the laboratory to successful field trials and product development, our work demonstrates that calcined clay concrete is more than just a concept—it can be applied on a large scale. Our field trials confirmed its workability and pouring performance, with the concrete's appearance and performance being similar to traditional blends." He noted that developing multiple blend formulations will help secure future supply chains while supporting the construction industry's decarbonization goals.
Following the successful completion of the product development phase, Boral Limited reported growing industry interest in trial collaborations and partnerships to explore the adoption of calcined clay concrete in future infrastructure and construction projects. This development highlights the role of innovative cement alternatives in helping the construction industry reduce emissions while maintaining performance and reliability.
