摘要
实验研究了碳化硅．铁精矿砂组合比例改变对混凝土电磁屏蔽性能的影响，在0．3~500MHz频段，该组合获得的屏蔽效能均不超过7dB，在500MHz1．5GHz有7～15dB的屏蔽效果，并有屏蔽吸收峰出现；通过在碳化硅．铁精矿砂组合中引入手性体，在013～500MHz频段也获得了8～15dB的屏蔽效果。
Adding in SiC-Ferric oxide in diffident weight percents, the electromagnetic shielding efficiency of composite concrete were researched with experiment, for the combinations, the electromagnetic shielding efficiency is below 7dB in range of 0.3-500MHz, and obtained 7-15dB with a absorption kurtosis in range of 50MHz-1.5GHz; by adding some chiral media in combination of SiC-ferric oxide, the shielding efficiency is achieved 8-15dB in range of 0.3-1000MHz too.
