In this study, we examined the liquid carbonation reaction using recycled aggregates as an industrial by-products. This research deals with carbon fixation with a precipitation reaction utilizing 5 wt% and 30 wt% alkanolamine absorbents in an aqueous calcium oxide solution. Unlike carbon fixation operated at high temperature and pressure that consumes a lot of energy, we conducted experiments at moderate temperature (303.15 K) and pressure (1 atm). By adding calcium oxide solution into the carbon dioxide saturated solution, carbonated recycled aggregate was formed. To verify the physical properties of products, XRD analysis was performed and SEM images were obtained.
