Original Abstract

The present paper deals with the application of impedance spectroscopy method to test cement-based composites after their exposure to high temperatures. A type CEM I Portland cement, siliceous sand and shredded automobile tires were used to prepare mortar specimens. Various mixtures, different admixture shredded tires and the polymer. The specimens were exposed to high temperatures (temperature range: 23 - 400 C). Monitoring of structural changes during subjection to thermal stress is an effective way to determine the reliability of specimen structure. Based on Debye's dielectric theory, the specimens were created dielectric models. Impedance spectra were obtained, while relative permittivity, loss factor and impedance were also measured. The results obtained at each temperature were an indicator of the structural changes and material reliability.
