Abstract: The utilization of industrial solid waste resourcesin preparation of cement-based electromagnetic wave (EMW) absorbing material is of significant importance for resource utilization and prevention & control of electromagnetic pollution in urban areas. In this work, by incorporating steel slag as the main admixture in the cement-based material and using a composite absorber consisting of graphite powder and carbon fiber, a double-layer structured cement-based EMW absorbing material was prepared. The optimized steel slag-cement matrix was obtained from series of mechanical and electrical tests. Then investigated the electrical properties and mechanism of steel slag-cement based materials reinforced by composite absorber, and got its' influence mechanism. Based on the design method of single-layer structure, a double-layer structure with exceptional EMW absorbing properties was designed following the gradual impedance principle. The results showed that the addition of steel slag and composite absorber in cement-based materials has a slight adverse effect on mechanical properties. However, it can significantly enhance the electric conductivity and EMW absorbing properties of the cement-based material. The double-layer structure significantly enhances the absorption performance of cement-based material. With the optimal design parameters obtained, the two formulations of absorbing materials achieve a minimum reflection loss of -29.79 dB and -36.66 dB, respectively. Additionally, they exhibit ultra-high effective bandwidths of 1.39 GHz and 1.37 GHz. This work provided a comprehensive explanation to the influence mechanism of steel slag-cement-based EMW absorbing materials reinforced by composite absorber. The proposed design method for double-layer structure EMW absorbing materials has excellent design flexibility and diversity, and has certain guiding significance for design and construction.
