PROBLEM TO BE SOLVED: To provide artificial building stone having high strength without adding an industrial product such as cement when producing an artificial stone (a consolidated product) by making slag as a principal raw material become consolidated through carbonation reaction. SOLUTION: When this artificial stone is made from a mixture, as a raw material, of slag from a steel-manufacturing process as a principal raw material with an additive, the slag as a principal raw material comprises at least one kind selected from a group consisting of granule slag, coarse grain-form one and small aggregated one, and at least part of the additive comprises water granulated slag. The mixture of the slag with the additive is made to consolidate and to be aggregated by CaCO3 formed through carbonation reaction as a binder.
