Low carbon footprint supplementary cementitious materials for concrete and blended cement from mineral carbonation

MCi Carbon have developed a carbon capture and utilisation technology that captures CO2 directly from industrial flue gases and transforms it into valuable industrial products such as silica to be used in concrete.

MCi Carbon and the University of Technology Sydney collaborated on this project to develop a technical foundation for the acceptance of MCi Carbon’s silica products as supplementary cementitious material to lower the embodied carbon of concrete.

In 2026, the team successfully used the product, Pozzlock, in a field trial with Boral.
