摘要：Wave-absorbing properties of ordinary concrete and pumice lightweight aggregate concrete which contained expanded perlite and carbon black were investigated in this paper. The results indicated that pumice lightweight aggregate concrete had ideal wave-absorbing properties. Within the scope of 2 similar to 18 GHz, the lowest reflectivity reached to -20 dB and better than the bandwidth of -5 dB up to 9 GHz. Meanwhile, the incorporation of proper carbon black absorber and expansion perlite can improve wave-absorbing properties.
