Research on Absorbing Property of Three Kinds of Cement-Based Material Blending Compositions

Article Preview

Abstract:

The absorbing performance have been tested and analyzed by taking cement as matrix, blending material silica fume and culver zed fuel ash, graphite and carbon fibers, nanoTiO2 and steel fibers for absorbing agent trial Sample, in the 8 ~ 18 GHz frequency band, the results indicate that silica fume and culver zed fly ash, nanoTiO2 and steel fiber and composite cement which made of Absorbing material has good absorbing property. Graphite and carbon fiber and cement composite made of the effectiveness of absorbing materials. Blending material absorbing properties of cement-based materials, the impact must be considered together, not the more the better, when blending material exceeding a certain threshold, its ability of wave-transparent enhance while absorbing property will be reduced finally.
