Abstract

Concern regarding the shielding effectiveness (SE) of building materials is gaining more response nowadays due to the awareness on the electromagnetic pollution (EMP) that is believed to results in disastrous consequence. A pure concrete inherently providing certain level of SE but it is not enough. Hence additional shielding and absorbing additives are added into the concrete. In this work MnxZnl,Fe204 will be added into the pure concrete to enhance its SE performance. The effect of microstructure, compositions, grain sizes, homogeneity, mixture volume of the MnxZnl,FezOc will be considered for the optimization in this mixture. The key component to determine the SE of concrete is their electrical characteristic (relative permittivity and relative permeability). The parallel plate which is proposed previously will be used to determine the electrical characteristic of material and it will also be used for SE measurement.
