An Experimental Study on the Development of Electromagnetic Shielding Concrete Wall System Using Conductive Materials for Shielding High-altitude Electromagnetic Pulse(HEMP)

HEMP를 대상으로 한 도전성 재료 혼입 콘크리트 전자파 차폐 벽체 시스템 개발에 관한 실험적 연구

In this study, the shielding properties of concrete with conductive materials as shielding material for electromagne- tic pulse(EMP) within 10kHz~18GHz were investigated. The shielding effectiveness of specimens were compared with different entrained materials. The shielding effectiveness were determined according to MIL-STD-188-125-1, IEEE-STD-299 at 28 days of concrete curing. The results of shielding effectiveness did not meet the criteria(80dB) severely.
