摘要：
The article presents the results of diagnostic tests of the concrete elements, subjected to fire. The as-sessment of selected methods suitability, mainly non-destructive, but also some destructive, used to determine the properties of the concrete subjected to high temperature, was verified. The aim of the study was to determine the relationship between selected diagnostic parameters (ultrasonic pulse ve-locity, rebound number) and the residual mechanical properties of the damaged concrete. It was found that ultrasonic pulse velocity in direct transmission is compliant with specimen compressive strength, moreover, this method allowed to determine the thickness of the damaged concrete layer.
