摘要

The influence of expanded graphite and nickel ferrite (NiFe₂O₄) expansion graphite on electromagnetic shielding effectiveness (SE) of cement paste were researched in this paper. The SE value of cement paste filled different modified graphite was measured by a coaxial flange method. Results show that the SE of cement paste filled expanded graphite inserted by Ni-ferrite could be substantially increased in the whole testing frequency band. Especially, the SE of cement paste was obviously improved in the low frequency band (30-1 000 MHz). The best SE of cement paste filled expanded graphite inserted by 15% Ni-ferrite was 26 dB.
