PURPOSE: An unsaturated polyester composite resin composition for a concrete mold panel is provided to obtain a concrete mold panel with high intensity and durability compared with general concrete. CONSTITUTION: An unsaturated polyester composite resin composition for a concrete mold panel includes 0.5~30 weight% of an unsaturated polyester resin, 50~80 weight% of inorganic filler, and 19.5~20 weight% of a shrinkage-reducing agent. The inorganic filler comprise filler and aggregate. The filler is fly ash with a powdery degree of 1,500~3,500 g/cm^3, steel-making dust with a powdery degree of 500~2,500 g/cm^3, or waste concrete microparticles with a powdery degree of 100~1,000 g/cm^3.
