摘要

It should be noted that as the matrix of cement-based wave-absorbing composites, cement not only plays the role of cementing material, but also has an absorbing wave capacity that should not be ignored. Therefore, the wave-absorbing property of cement within the frequency range of 1~18 GHz were studied with the arched testing method. The results show that with specimen thickness range of 5~30 mm, the positions of maximum wave-absorbing peaks do not change with different specimen curing period and surface roughness, but change to lower frequency region with the increase of specimen thickness; P·II cement has an absorption of 18 dB at the optimal thickness of 10 mm with bandwidth of 6 GHz at 8 dB absorption peak; and modified sulfoaluminate cement has maximum absorption rate of 16~22 dB at thickness of 5~20 mm with bandwidth of 2~3 GHz at 8 dB.
