Electromagnetic shielding has become more important in recent years as a result of increased electromagnetic environment pollution, its long-term health effects and information security in buildings. Therefore, the studies on building materials that can prevent electromagnetic emission have caused great attention. Additionally, accurate measurements of electrical characteristics properties of materials can provide scientists and engineers with valuable information to properly incorporate the material into its intended application for more solid designs or to monitor a manufacturing process for improved quality control. This paper mainly focused on the progress and prospective future of cementitious building materials by using waste metallic chips as a constituent for the purpose of electromagnetic shielding, wave absorbing activities and electrical properties of materials. For this purpose, natural sand was replaced in volume provided from different industrial areas in the production of cementitious composite, and these materials were examined to determine their electromagnetic shielding, absorbing capabilities and dielectrical constants. As a result, although reference sample has almost 7dB shielding efficiency, sample having iron chips (60%) has 18dB shielding efficiency which is known as good shielding material property value.
