Electromagnetic Wave Absorption Properties of Glass Fiber Reinforced Cement Filled with Carbon Black

Abstract:

In order to deal with the more and more serious problem of electromagnetic radiation pollution, cement-based composites were prepared by introducing glass fiber into cement as through wave reagent and carbon black as absorbing reagent . Arched testing method were used to test the reflection losses in the frequency range of 2~18 GHz. The results showed that the absorption properties were improved in high frequency compared with the pure cement. The filling ratio of carbon black and glass fiber as well as the thickness of samples had influence on the absorption properties. The lowest reflection loss of-11.2 dB was obtained at 18 GHz of 9wt.% glass fiber and 5wt.% carbon black filled cement with thickness of 10mm. The new material can be used for building indoor electromagnetic radiation protection.
