The cement industry is responsible for approximately 10% of greenhouse gas (GHG) emissions in the industrial sector, with most emissions occurring during the cement clinker production process. To address this issue, the cement industry is making efforts to reduce GHG emissions by developing technologies such as raw material substitution, improving process efficiency using new low-carbon heat sources, and employing CO₂ capture and utilization techniques. This study conducted foundational experiments to contribute to the reduction of CO₂ emissions in the cement industry by utilizing a CO₂ recycling technology called mineral carbonation. In this study, calcium silicate cement(CSC) was manufactured at the laboratory scale to convert CO₂ into a mineral form, and analysis was performed on the carbonate mineral phase and strength development. The manufacturing and analysis results of CSC clinker confirmed the formation of key minerals, namely wollastonite and rankinite. Furthermore, through CO₂ curing of CSC, carbonate minerals including calcite and aragonite were formed. The compressive strength measurements of carbonated CSC paste specimens confirmed the development of strength. In conclusion, this study demonstrates the feasibility of CSC production and the manifestation of compressive strength through CO₂ generation, contributing to the potential reduction of CO₂ emissions in the cement industry.
