Cement concrete presents a significant opportunity for carbon dioxide (CO 2) 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.
26 Ιουν 2024 · Producing cement offers a large opportunity for CO2 sequestration but is hindered by low CO2 capture efficiency and high energy consumption. Here, CO2 injection into a cement suspension...

9 Δεκ 2022 · This work introduces the important significance of CO 2 absorption by using cement-based materials, and summarizes the basic characteristics of carbonation of concrete, including the affected factors, mathematical modeling carbonization, and the method for detecting carbonation.
8 Φεβ 2021 · By accounting for these factors, we determine the net CO2 benefit when CCU concrete produced from CO2 curing and mixing substitutes for conventional concrete.
30 Σεπ 2023 · Abstract. The concrete industry, which heavily relies on Portland cement, contributes to about 5–8% of the global CO 2 emissions on its own. This research aims to investigate the feasibility of permanently capturing CO 2 within concrete.
