Abstract
PURPOSE:To improve a radio wave failure of a television, a radio receiver or a radar due to a soundproof wall mounted on the side of a road or a railway line, the outer wall of a building or other construction wall by employing an absorber made of cement composition containing radio wave absorbing substance. CONSTITUTION:As a radio wave absorbing substance, conductive materials, such as aluminum, nickel, carbon or semiconductor silicon single crystal, etc., high dielectric materials, such as alumina or barium titanate, or a magnetic material, such as ferrite. After these materials are formed in powder or fibrous state, one or more radio wave absorbing substances are mixed with cement composition. This absorber is employed as a soundproof wall or a construction wall. Thus, radio wave failure, such as a television, a radio receiver and a radar, etc., can be removed, and radio wave absorbing effect is not reduced over a long period with high durability.
