Abstract:
The electromagnetic shielding properties of coke cement materials have been investigated experimentally an theoretically. Calculated and measured values are in close agreement. The conductivity of six samples of coke - cement has been determined. Repeated measurements after 19, 29, 30, 32, 33, 36, and 191 days show the effect of aging on the conductivity of coke - cement materials. These materials were found to be capable of shielding electromagnetic interference of the type that would emanate from the average administrative building under certain circumstances. Eight types of material available commercially and used as construction material were evaluated as electromagnetic shields. Author
