본 연구에서는 시멘트에 EMP차폐 성능을 부여하고자 탄소섬유를 사용하여 EMP차폐 성능평가를 실시한 결과 측정 주파수 범위에서 50dB이상의 차폐 성능을 나타냈다. In this study, a carbon crab admixture was used to impart EMP shielding performance to cement. As a result of the EMP shielding performance evaluation, the shielding performance was over 50dB in the measurement frequency range.

In this study, the purpose of this study was to develop concrete structural walls including the functions of the barrier and EMP shielding performance as the concrete structure itself. Mix of highly challenging metal fibers in super-high strength concrete. The EMP measurement frequency was evaluated for EMP card performance using a waveguide measurement method in the range of 0.8 GHz to 1.0 GHz. Performance evaluation shows that steel fiber has an increased compression strength and shielding effect as amount of mixing increases. In addition, shielding performance increased due to the increased thickness of the specimen. Therefore, it is judged that steel fiber is a good blend for shielding effects.

The EMP slip rate was compared with the general concrete using the electric arc furnace slag as an aggregate. Experimental results show that the shielding rate of concrete specimens using electric arc furnace slag increases. It is considered that the shielding rate is increased due to the high Fe content in the components of the electric arc furnace slag aggregate.
