PROBLEM TO BE SOLVED: To provide a resin concrete composition giving a low-shrinkage hardened molded product of no crack development with high mechanical strength, thus needing no low-shrinkage agent, and to provide a method for producing the molded product. SOLUTION: The resin composition for resin concrete molding use comprises (A) a resin composition comprising (a1) an unsaturated polyester obtained by reaction between an unsaturated dibasic acid, a saturated dibasic acid and a dialkylene glycol and/or alkylene glycol and (a2) a crosslinkable monomer, (B) a resin composition comprising (b1) an unsaturated polyester comprising a dicyclomaleate-butanediol adduct and (b2) a crosslinkable monomer, (C) a hydroxy-terminated polybutadiene, (D) aggregate and (E) a filler.
