Increasing Shielding Capabilities of Cement Mortars by Fly Ash Addition

Abstract:

The magnetic and dielectric behavior of Portland cement mortars with various fly ashes (waste from the thermoelectric power plant) with a Fe2O3 content of 13.8 % was studied. The dielectric losses, tgd, the real component of the dielectric permeability, e’,and the real magnet permeability, ì, the parameters with which we calculated the shielding coefficients, a, of the investigated samples, have been determined for the purpose of determining the screening capacity of the investigated samples by magnetic and dielectric spectroscopy in the 50 Hz - 3 kHz (ELF) range. Following experimental data processing, it was found that by increasing the hematite microstructured hematite Fe2O3 content of mortar samples (by fly ash addition) increased shielding capacity in the ELF domain, recorded increases for shielding coefficients, a, to an addition of up to 40 % fly ash, being up to 14.5 times at 50 Hz and up to 21 times at 3 kHz.
