Electromagnetic Shielding Effectiveness of Cement Based Materials with Scrap Tires Wire - FeCuNbSiB Amorphous Alloy Powder

Abstract:

Article Preview

Replacement of steel fiber by scrap tires wire as shielding agent in cement-matrix composites was discussed in this paper. The electromagnetic shielding effectiveness (SE) of cement based composites materials containing FeCuNbSiB amorphous alloy powder and scrap tires wire were measured with coaxial planar-spectrum analyzer method. Results show scrap tires wire can effectively enhance the SE of cement composites in tested frequency range. The shielding effectiveness at 1.5GHz is 14.1 dB at a scrap tires wire content of 1.3 vol.% in cement paste. The SE of composites that simultaneously contain scrap tires wire and FeCuNbSiB powder is higher than singly use these shield agents.
