Cement concrete presents a significant opportunity for carbon dioxide (CO2) capture, utilization, and storage through carbonation treatment. This process involves carbonating binders, industrial waste materials, and recycled aggregate concrete, which can subsequently be integrated into fresh concrete mixtures. This review focuses on the current research landscape regarding the use of CO2 in producing low-carbon and sustainable concrete, emphasizing developments over the past decade (2014–2024). The paper begins by outlining the properties of CO2 and exploring its potential applications within the concrete industry. It then summarizes and compares the various carbonation methods applied to cement concrete and classifies the different approaches to CO2 utilization in concrete production. Additionally, the review examines the carbonation mechanisms of binders and the development of low-carbon concrete, aiming to enhance the understanding of how carbonized components affect the performance of cement-based materials. Finally, the review explores typical commercialized technologies for CO2 utilization in producing low-carbon concrete. The discussions and findings presented are anticipated to provide valuable insights into the application of CO2 in the concrete industry, thereby facilitating the production of low-carbon and sustainable concrete.
