Abstract

The growth in the transport industry results in more accidents, which often include fire in locations with the concrete structures, which also effects its lifetime and its functionality. After any case of fire loading it is required to verify structure’s condition. One way how to assess the risks connected with further usage of the structures after being exposed to the fire is the non-destructive testing. This paper is dealing with non-destructive measurement of changes of electric parameters of the cement based mortars subjected to the high temperatures.
Způsob, jak posoudit rizika spojena s narušením struktury, poté, co byla vystavena ohni je nedestruktivní zkoušení. Příspěvek se zabývá nedestruktivním měřením změn elektrických parametrů cementové maltové směsi vystavené vysokým teplotám.
