Construction of Conductivity Concrete as Modern Material in Electromagnetic Shielding
Mohammad Mardani , Mohsen Kamyab sharif
Abstract:   (5132 Views)
Using Electromagnetic waves shields is the method in Passive Defense that helps to reduce damages caused by modern Electromagnetic threats such as EMP and HMP. The Substances which used in shields structure should have special characteristics like relevant electrical and magnetic conductivity coefficients. This Research is related to construction of special concrete which has high electrical conductivity for reduction and elimination of high power electromagnetic waves threats as electromagnetic shields in any kinds of critical and infrastructural establishments. In this paper firstly we compared the reflection of X-band wave on the pieces of the pure concrete with its reflection on concrete block 5*5*5 Cm mixed by 5 percent carbon black. In another experiment, the effect of concrete thickness on transmittance and wave attenuation was measured and finally, in another experiment, the effect of carbon black mixed concrete was investigated. The best wave absorption resulted at the 2 Cm thickness and 10% carbon black equal to 19.35 -dB.
Keywords: Electromagnetic Threats, Conductive Concrete, Electromagnetic Shielding, Carbon Black, EMP.
