Concrete is the most used man-made material in the world. Cement production accounts for 5-8% of anthropogenic CO2 emissions. Efforts to reduce cement usage and to utilise CO2 via various means to reduce the embodied carbon of cement-based materials have been a continuous task in both academia and industry. This webinar presents the recent research and advances on carbon reduction and utilisation in cement-based materials, including low carbon cements, supplementary cementitious materials, and carbon sequestration via pre-carbonation, acceleration carbonation curing, and service life carbonation. Mechanisms of these approaches and their influence on concrete performance in terms of mechanical properties, durability, and microstructures are summarized. Overall, this talk summarises a roadmap for emerging carbon reduction and utilisation techniques that contribute to embodied carbon reduction of cement-based materials for construction.
