Abstract

This review examines methods for utilizing CO2 in construction materials to reduce the carbon footprint of cement and concrete production. Key approaches include direct carbonation of calcium silicates through CO2 curing, use of industrial by-products as supplementary cementitious materials activated by carbonation, production of alternative binders and aggregates via CO2 treatment of waste materials, injection of CO2 into fresh concrete mixtures, and use of CO2-dissolved mixing water. Both academic research and emerging commercial technologies are covered. While these methods show promise for enhancing material properties and sequestering CO2, challenges remain in optimizing reaction conditions, ensuring long-term durability, and scaling up processes. The review concludes that CO2 utilization presents a multi-faceted opportunity to create more sustainable construction materials while sequestering greenhouse gases, but further research and development is needed to fully realize its potential for decarbonizing the cement and concrete industry. Overall, these approaches offer innovative pathways to address the significant environmental impact of construction materials production.
