We focus on the carbon powder as a conductive material which provides new feature and added value to concrete. In this study, the electromagnetic wave shielding property of mortar with carbon powder was examined by transmission test and reflection test.Also, complex specific permittivity that indicates the electrical property of material was calculated from experimental result of transmission test. Accordingly, in the transmission test, transmission amount turned out to be decreasing along with increase of carbon powder additive rate, and electromagnetic wave shielding property was improved. It was found that presumed complex specific permittivity tends to be largeboth on real part and imaginary part, along with increase of carbon powder additive rate.
