Abstract

In this research, The basic physical properties and EMP shielding performance by thickness were evaluated for optimum composition of EMP shield concrete that can be applied on-site by mixing carbon-based materials with high conductivity into concrete that uses electric furnace oxidized slag (EOS). As a result of the evaluation, it was confirmed that the slump decreased as the amount of mixed carbon fib er (CF) increased, and increased when milled carb on (MCF) was mixed. As for the compressive strength, it was confirmed that EOS enhanced the strength compared to NA, and it was confirmed that the strength decreased when CF and MCF were mixed. As the thickness of the EMP shielding measurement increases, the shielding rate increases, and it was confirmed that the type of conductive material and the thickness of the test specimen have a greater influence on the shielding rate than the Amount of conductive material added. As a result of a comparative evaluation, EOS CF 0.2 is considered suitable for EMP shield concrete formulation.

본 연구에서는 금속성분을 다량 함유한 전기로산화슬래그(EOS)를 골재로 활용한 콘크리트에 도전성이 높은 카본계 재료를 혼입하여 현장적용이 가능한 EMP 차폐 콘크리트의 최적배합을 도출하고자 기초적인 물성과 두께별 EMP 차폐성능을 평가하였다. 평가결과 슬럼프는 카본섬유(CF)의 혼입량이 증가할수록 저하, 밀드카본(MCF) 혼입시 증가하는 것을 확인할 수 있었다. 압축강도는 EOS가 NA에 비해 강도를 증진시키는 것을 확인할 수 있었으며, CF 및 MCF 혼입시 강도가 저하되는 것을 확인할 수 있었다. EMP 차폐 측정결과 두께가 증가할수록 차폐율이 증가하였으며, 도전성 재료의 첨가량보다 도전성 재료의 종류 및 시험체의 두께가 차폐율 증가에 영향력이 더 큰 것을 확인할 수 있었다. 종합적으로 비교평가를 진행한 결과 EMP 차폐 콘크리트 배합으로 EOS CF 0.2가 적합한 것으로 사료된다.
