Correlation between Electrical Conductivity and Shielding Effectiveness of Cementitous Composites according to length and volume fraction of steel fiber

강섬유의 길이 및 혼입률에 따른 시멘트 복합체의 전기전도도와 차폐효과의 상관관계

The purpose of this study is to compare and analyze the effect of the length and volume fraction of smooth steel fiber on the electrical conductivity and shielding effectiveness of cementitious composites. As the length and volume fraction of the fiber increase, the movement of electrons becomes active and the formation of a conductive path becomes advantageous, thereby increasing electrical conductivity. Accordingly, the electrical conductivity and the shielding effectiveness showed a very close relationship. Thereafter, it is judged that research is needed to increase the shielding effect.
