Concrete-based composites with the potential for effective protection against electromagnetic radiation: A literature review

This review explored areas related to the use of concrete-based and cement- based composite materials that can protect against electromagnetic radiation. Based on their potentially desirable properties related to protection against electromagnetic radiation, this paper discusses four different types of admixtures in concrete composites: fly ash, carbon nanotubes, titanium dioxide, and zinc ferrite. The analysis of electromagnetic radiation protection was studied for the frequency range of non-ionizing radiation up to 10 GHz, where wireless communication devices typically operate. This review paper also discusses the influence of these admixtures on the other properties of concrete. This paper can serve as a resource for determining the most optimal and effective methods for protecting against electromagnetic radiation using concrete composite elements.
