PROBLEM TO BE SOLVED: To provide a producing method of a non-fired agglomerate rapidly aged at about the vaporization temp. of water, holding sufficient water of the green agglomerate and having sufficient strength. SOLUTION: When a green agglomerate obtained by mixing a binder 2 to be cured by forming a hydrate and/or carbonate and water 3 with a raw material 1 composed of one or more kinds of ore powder, metal oxide dust and carbon material-containing powder and molding is aged under an atmosphere of a gas 6 containing steam and CO2 to be cured for a short time, the aging temp. is controlled to a temp. ranging±20 deg.C of the b.p. of water and the water content in the green agglomerate under aging is controlled to 2-12 wt.%.
