NOVELTY - Magnetic absorbing concrete structure comprises a surface layer and a bottom layer. The surface layer includes expanded polystyrene and Portland cement. The expanded polystyrene has a filling ratio of 40-70 vol.% and a particle diameter of 2-6 mm. The bottom layer includes graphene/triiron tetraoxide powder and Portland cement. The amount of graphene/triiron tetraoxide powder is 5-15%. The volume ratio of graphene and triiron tetraoxide is 2:1-1:2. USE - Used as a magnetic absorbing concrete structure. ADVANTAGE - The structure reaches absorbing ability to more than -12 db to enhance the absorbing performance.
