“…It is worth noting that for the asextruded ZK60-1.0Ce alloy the EMI SE kept as high as 71-81 dB at the whole frequency range, which even meets the military requirement of 60-120 dB [11]. Wen and Chung [23] elevated the EMI SE of cement up to 70 dB by adding stainless steel fibers; however, the thickness of the cement composite was 9.5 mm, which was 4.75 times higher than that of the ZK60-1.0Ce alloys. The EMI SE of as-extruded ZK60-1.0Ce alloy was able to be improved further by direct artificial aging, as shown in Fig.…”

“…Due to their high electrical conductivity and ferromagnetic character, steel fibers are attractive for shielding. 31 However, the high density of steel requires viscosity enhancement, which is provided by the use of graphite flakes. Without the graphite flakes, the steel fibers form agglomerates, as observed in this work.…”

“…The subject paper neglected the paper by Wen and Chung [1] that reported a shielding effectiveness of 70 dB (1.5 GHz) for cement containing 0.72 vol.% stainless steel fiber of diameter 8 lm. This value of the shielding effectiveness is the highest that has been reported for cement-based materials.…”
