ABSTRACT:
Method and apparatus for making electrically conductive concrete articles ed for electromagnetic shielding, the invention also includes the articles of manufacture formed according to the method. Concrete articles formed according to the method of the invention are reinforced with magnetized metallic fibers, preferably steel fibers, a substantial portion of the fibers contacting nearby fibers to provide electrical continuity through the article. Contact between fibers is enhanced according to the invention by vibration of the concrete/fiber mix during forming of the electrically conductive concrete article.
