This research article explains the synthesis and scale-up of calcium carbonate (CaCO3) from waste concrete as calcium-rich material by an inorganic carbonation process. The operating parameters include S/L ratio, HCl concentration, contact time, and extraction pH were investigated. The calcium hydroxide (Ca(OH)2) was synthesized by reaction between calcium chloride (CaCl2) and sodium hydroxide (NaOH), which induced the spontaneous reaction of CaCO3 without additional energy consumption. The productivity of CaCO3 was 1 kg/d in the laborator
