The shielding effectiveness of carbon nanotube reinforced concrete composite is analyzed by using a reverberation chamber. The frequency band is 0.8-8 GHz and the weight percentages of carbon nanotube are 0, 1, 3 wt%. Results highlight that about 30 mm thick of 3 wt% reinforced concrete composite is able to perform a shielding effectiveness greater than 15 dB around 2 GHz and up to 30 dB at 8 GHz. The here reported results suggest the employment of carbon nano-powder reinforced concrete in building structures, having issues related to the electromagnetic interference mitigation, such as the influence on the medical devices working in hospital environments as well as the increasing of protection against electromagnetic attacks to strategic targets and sensible places.
