description To prevent drastic climate changes due to global warming, it is necessary to transition to a carbon-neutral society by reducing greenhouse gas emissions in all industrial sectors. This study aimed to develop carbon utilization sequestration technology that uses the concrete slurry water generated during the production of concrete as a new CO(2) sink to reduce CO(2) emissions from the cement industry. This was achieved by performing supercritical CO(2) carbonation by varying the concrete slurry waste (CSW) ratio. The study’s results confirmed that, according to the CSW ratio (5 to 25%), complete carbonation occurred within only 10 min of the reaction at 40 °C and 100 bar.
