钢渣中含有大量的铁的氧化物,且以多种状态存在。在1～18GHz内采用弓形反射法研究钢渣掺入水泥后的吸波性能。结果显示:吸收峰的位置基本不受养护时间和掺量的影响,但随试样厚度的增加会表现出向低频区移动;随试样厚度的增加,在低频区1～8GHz波段范围内,最大吸收率从23dB逐渐降低到7.5dB,而在高频区10～18GHz波段范围内,吸收率先逐渐增加达到最大值后再降低;当掺30%(质量分数)粉磨60min的钢渣,复合材料的厚度为25mm,养护285d时,在13～18GHz波段内吸收率最大达到12dB,大于8dB的带宽为5GHz,表现出较好的吸波性能。 Slag contains a large amount of iron oxide, and exist in a variety of states. In the 1 ~ 18GHz arc reflection method used to study the slag absorbability after cement incorporation. The results show that the position of the absorption peak is basically unaffected by the curing time and dosage, but it moves toward the low frequency region with the increase of the thickness of the sample. With the increase of the thickness of the sample, in the range of 1 ~ 8GHz in the low frequency range, Absorption rate decreased from 23dB to 7.5dB, while in the high frequency range from 10 to 18GHz, the absorption rate first increased and then decreased to the maximum value. When the slag content of 30% (mass fraction) When the thickness is 25mm and the curing time is 285 days, the maximum absorption rate reaches 12dB in the band of 13-18GHz, and the bandwidth of more than 8dB is 5GHz, which shows better absorbing performance.
