This study was conducted to investigate the properties of cement paste and mortar using carbonated water as mixing water for the development of CCUS(Carbon Capture Utilization and Storage) technology in the cement industry. As a result of the experiment, it was found that using carbonated water has a hydration delay effect at the early age and can secure a equivalent strength compared to the control cement composites. Therefore, the use of carbonated water confirmed the applicability in the cement-concrete industry.
