Characterization of Thermal Stress of Building Materials Containing Rubber Granulate by Alternating Electric Field
Original language description
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. The specimens differentiated in whether or not a 10 % w/w acrylic polymer binder (polymer dispersion 20 % w/w to cement mass) addition to the mortar mixture was used. The specimens were exposed to high temperatures (temperature range: 25-400 degrees of Celsius). Monitoring of structural changes during subjection to thermal stress is an effective way to determine the reliability of specimens structure. Based on Debye's dielectric theory, the specimens were used as dielectric models. Impedance spectra were obtained, while relative permittivity, loss factor and impedance were also measured. The results concerning electrical parameters and permittivity at each temperature were an indicator of the structural changes and its reliability.
