Absorbing and Mechanical Properties of Cement-Based Composites with Nano-Titanic Oxide Absorbent
The cement-based composite absorbing materials was made of portland cement and nano-titanic oxide absorbent. The relationship of electromagnetic wave reflectivity and nanometer TiO2 contents, dispersed means, samples thickness, and effect of nanometer titanium oxide on mechanical properties of cement-based composites were discussed in details. The experiment results revealed: 1) The reflectivity of cement-based composites with nanometer titanium oxide is less than -7 dB at 8~18 GHz frequency range; 2) The least reflectivity is -16.34 dB at 16.24 GHz and the bandwidth for -10 dB is 4.5 GHz; 3) The mechanical properties of cement-based composites with nanometer titanium oxide are superior to that of cement paste.
