PROBLEM TO BE SOLVED: To stably produce a high strength carbonated solid. SOLUTION: The method for producing the carbonated solid comprises bringing a raw material mainly having an uncarbonated Ca-containing raw material into contact with carbon dioxide in a moisture-containing state and solidifying the raw material by carbonation reaction. In the method, a fine powder raw material free from the uncarbonated Ca, and preferably, having particle diameters of≤100μm is mixed with a powdery and granular uncarbonated Ca-containing raw material having fine powder content, and the mixed raw material is solidified by the carbonation reaction.
