Summary: | To provide a hydraulic composition for an additional production device high in strength development, particularly, in initial strength development and reduced in the generation of defects caused by gas and a graphite spheroidizing defect in the production of a cast, and a method for producing a mold.SOLUTION: There is provided a hydraulic composition for an additional production device in which a polymer is comprised by 2 to 12 pts.mass to 100 pts.mass of a binder including calcium aluminate by 50 to 100 pts.mass. Also there is provided a method for producing a mold where a mold is molded by using an additional production device and the hydraulic composition for an additional production device.SELECTED DRAWING: None
