금속용사 마감공법을 적용한 콘크리트의 전자파 차폐효과에 관한 실험적 연구

Abstract

Recently, it is increased that the interest of the public harmfulness of electromagnetic wave. Many studies report harmfulness of human body. And electromagnetic wave from electric machine cause problem of electric circuit. So, electromagnetic wave shielding material is one of the countermeasure of the electromagnetic wave problem. But, existing shielding material, like iron plate, copper plate is lack of construction ability. As on this study, we find how much of shielding efficiency of metal spraying finishing method by experimentation of shielding box and compare with some metals, copper plate and metal spraying on the concrete plate.
