(57) [Problem] To provide a structure such as a wall, a ceiling, a floor, and the like, which has magnetic permeability, can stop articles without using pins or adhesives, and is excellent in radiation shielding properties. The task is to provide. An electric furnace oxidized slag fine aggregate is mixed with a structure such as a concrete wall to impart magnetic permeability. Since the memo paper 22 and the like can be fixed to such a concrete wall 21 with the magnet 23, there is no piercing or sticking of an adhesive with a pin, and the magnetic shielding property and the radiation shielding property are excellent. . |
