The assessment of mechanical properties of thermally stressed composite materials using radio frequency electrical field
(IOP Publishing, 2018-07-01)
The main topic of this paper is the testing of cement-based composite materials that were stressed by high temperature. Impedance spectroscopy has been used as a non-destructive measurement method. The specimens were made ...
Monitoring of concrete hydration by electrical measurement methods
Analysis of impedance spectra of inhomogeneous materials is a part of the impedance spectroscopy which is still waiting for its development. Materials having higher electric resistance values (over 500 kohm) can be considered ...
Flexure response of thermal loaded concrete specimens by acoustic emission method
(EDP Sciences – Web of Conferences, 2017-05-24)
The response to fire of concrete structural members depends on the thermal, mechanical, and deformation properties of concrete. These properties vary significantly with temperature depending on the composition and ...
