摘要：In this paper, five groups of cement concrete specimens reinforced by carbon nanofibers (CNFs) were prepared with different fiber content of 0%, 0.1%, 0.2%, 0.3% and 0.5%, the electromagnetic shielding effectiveness (SE) and the mechanism of shielding were analyzed. The results show that, when the frequency of electromagnetic wave is higher than 2 GHz, with the increase of frequency, the improvement gradually increases; When the frequency is 18 GHz, the SE reaches the maximum; CNFs can improve the SE of concrete material by improving its conductivity and the loss of electromagnetic wave.
