PURPOSE: A bio-plastering material composition as a construction material is provided to effectively shield electromagnetic waves generated in living environment and to improve workability in its construction. CONSTITUTION: The bio-plastering material composition for an electromagnetic wave shielding, which includes an active material, a binding material, a filler, resin, blending components and additives, comprises, based on 100 pts.wt. of the binding material, 5-50 pts.wt. of a mixture of a graphite powder having 1.0 mm or less of particle size which is obtained by wet-curing, drying and grinding graphite waste generated from an electric furnace of an iron-making plant and a zeolite powder with a ratio of 5:3-10 and 30-70 pts.wt. of a light-burnt dolomite having 0.1-1.0 mm of particle size as a far-infrared emitting material. The graphite waste as an electromagnetic wave shielding agent comprises 10 pts.wt. or more of magnesia-carbon.
