AN ELECTROMAGNETIC RADIATION SHIELDING MATERIAL

摘要

A shielding material comprises at least one basic building material and at least one shielding component capable of reflecting or absorbing electromagnetic radiation. The shielding material optionally includes a hydraulically settable binder or cementitions material. The shielding components may be natural materials or direct or derived by-products of an industrial process. The shielding component may comprise a combination of graphite, especially kish graphite, and carbon black, especially acetylene black.
